Which Brand is Best

Choosing Between Hello Mary vs Simply Mary vs Grooby

Hello Mary

Hello Mary has a large rotating catalog with many flower, smalls, rosin, concentrate, vape, edible, bundle, and sale listings. That kind of product flow can be helpful for shoppers who like browsing new options, but freshness should still be checked at the product level by looking at the specific listing, COA documentation, and current availability.

SimplyMary

SimplyMary also appears strong on product freshness because its site highlights new arrivals, best sellers, flower categories, concentrate formats, vapes, edibles, and shop-by-effect navigation. It is built more like a modern product catalog, which makes it useful for shoppers who want frequent choices across different formats.

Grooby

Grooby takes a more curated approach to freshness. Instead of offering a huge marketplace-style menu, Grooby focuses on classic strains and a more focused set of product formats, including flower, pre-rolls, vapes, gummies, and Thai sticks. For shoppers who prefer a simpler, fresher-feeling selection around recognizable classic strains, Grooby has the strongest positioning.

Hello Mary

Hello Mary offers several potency-focused formats, including premium flower, smalls, rosin, diamonds, vapes, and edibles. Because the catalog is broad, potency and effects should be judged product by product rather than assumed across the entire store. Some products may be better suited for shoppers looking for stronger flower or concentrates, while others may be more moderate.

SimplyMary

SimplyMary also offers a wide potency range across flower, concentrates, rosin, vapes, pre-rolls, and edibles. Its shop-by-effect categories can help shoppers browse by desired experience, such as sleep, chill, euphoric, creative, or energized. As with Hello Mary, potency depends on the specific product, format, and COA.

Grooby

Grooby is best positioned for shoppers who want familiar classic strains across simple product formats. The appeal is not just potency, but the pairing of classic strain nostalgia with flower, pre-rolls, vapes, gummies, and Thai sticks. For users who want a clear and familiar shopping experience rather than a huge concentrate-heavy catalog, Grooby is the better fit.

Hello Mary

Hello Mary includes COA documentation on some product pages, which gives shoppers a way to review product details before buying. Because the store carries many product types and a wide range of listings, the safest approach is to check the individual product page before purchase.

SimplyMary

SimplyMary lists Certificates of Analysis as a site resource and also presents customer-facing trust messaging around COAs. That gives SimplyMary a strong transparency angle, especially for shoppers comparing flower, vapes, concentrates, and edibles. Still, buyers should review the actual COA for the product they plan to purchase.

Grooby

Grooby Shop also provides COA access and keeps the shopping experience more curated. That makes transparency easier to understand for customers who do not want to sort through a large marketplace. Grooby’s advantage is the combination of clear COA access, classic strain positioning, and a simpler product lineup.

Hello Mary

Hello Mary has one of the widest selections in this comparison. Its menu includes flower, premium buds, small buds, greenhouse flower, pre-rolls, concentrates, premium rosin, rosin, diamonds, vapes, bundles, edibles, accessories, apparel, and sale products. For shoppers who want variety above all else, Hello Mary is a strong choice.

SimplyMary

SimplyMary also has a very wide product range. Its catalog includes classic flower, boutique flower, flower smalls, pre-rolls, hash holes, cold cure, fresh press, full melt, thumbprints, jams, diamonds, badder, crumble, vapes, edibles, accessories, apparel, and sale products. It may be the most complete option for shoppers who want flower plus a deeper concentrate menu.

Grooby

Grooby offers a more focused range: THCA flower, THCA pre-rolls, THCA vapes, THCA gummies, Thai sticks, and classic strains across multiple formats. It does not appear as broad as Hello Mary or SimplyMary, but it is more curated and easier to understand.

Hello Mary

Hello Mary has a wide price range, including sale products, product variants, points-based purchase incentives, and free ground shipping over $99. That makes it a strong value option for shoppers who like browsing deals and comparing different product sizes or formats.

SimplyMary

SimplyMary also offers a broad range of products and promotes free shipping over $99. Its catalog includes both premium-style options and sale navigation, so value depends on what the shopper is buying: flower, smalls, rosin, vapes, edibles, or concentrates.

Grooby

Grooby is better framed as a quality-value pick rather than the cheapest option. The value comes from a clearer product experience, classic strain appeal, COA access, and a more focused brand identity. For shoppers who want a curated hemp experience instead of chasing the lowest price, Grooby offers the strongest quality value.

Hello Mary

Hello Mary promotes free ground shipping on orders over $99 and free priority shipping on orders over $199. The site also links to shipping and returns policy resources, which is useful for shoppers who want to check fulfillment details before buying.

SimplyMary

SimplyMary promotes free shipping on orders over $99 and includes shipping and returns resources in its site navigation. That gives it a clear shipping advantage for shoppers who meet the free-shipping threshold.

Grooby

Grooby Shop includes 3–5 day shipping messaging and customer support resources, along with COA access and a more guided shopping experience. For shoppers who care about clarity, support, and a less overwhelming checkout path, Grooby is the stronger experience-focused choice.

It is also the strongest choice if you prefer a brand with personality, familiar strain names, and a more guided product lineup instead of a massive marketplace.

Choose Hello Mary if…

You want a broad THCA marketplace with frequent product options

Hello Mary is a good option if you want lots of product types to choose from, including flower, smalls, pre-rolls, concentrates, rosin, diamonds, vapes, edibles, bundles, accessories, and sale products. It makes sense for shoppers who enjoy browsing a larger catalog and comparing many products before buying.

Choose SimplyMary if…

Frequently Asked Qustions

All three brands sell hemp-derived THCA products online, but legality depends on your state’s current hemp and THCA rules. Before ordering, check whether the brand ships to your state and review local regulations.

These brands position themselves as online hemp/THCA retailers, not traditional medical dispensaries. In most cases, shoppers do not need a medical card, but age verification and state shipping restrictions may still apply.

Grooby is the easiest option for shoppers who want a simpler, more guided buying experience. Hello Mary and SimplyMary have larger catalogs, which is great for browsing, but can take more time to compare.

Grooby is the better fit for classic strain appeal because its brand is built around retro cannabis nostalgia, familiar strain names, and a curated hemp experience.

SimplyMary is a strong fit for concentrate shoppers because the comparison notes a deeper concentrate menu, including rosin, hash holes, cold cure, fresh press, full melt, thumbprints, jams, diamonds, badder, and crumble.

Not always. Lower prices can be useful, but you should also compare COA access, product format, freshness, shipping policies, and whether the brand’s catalog matches what you actually want to buy.

Product Details

Get 14g of Cold-Cured Flower — fresh, green, and full of flavour.
Old-school strains changed colour because of how they were cured. We use a modern cold-cure in a dark room, so Acapulco Gold stays green and tasty while keeping its classic character. Same genetics, just a better cure.

And it’s the same with strains like Panama Red — it isn’t bright red because we don’t use dyes. You’re getting the real genetics, cured the right way.
