The Complete 4/20 Guide: History, Best Deals, and How to Shop Smart

April 20 — or 4/20 — is the cannabis industry's Black Friday. It's the single biggest sales day of the year at most legal dispensaries, and the discounts reflect it. Flower, pre-rolls, edibles, vapes, concentrates — everything goes on sale, often at the deepest discounts a store offers all year. The holiday itself has murky origins. The most credible story traces it back to a group of California high schoolers in the 1970s who used '420' as a code for meeting up at 4:20pm to smoke. The term spread through Grateful Dead fan networks in the '80s, then into mainstream cannabis culture by the '90s. By the time legalization started rolling out state by state, April 20 had become the industry's de facto holiday. Why does this matter for shopping? Because dispensaries have turned 4/20 into a competition. Every licensed store tries to offer the most aggressive promotions possible — tiered discounts, BOGOs, vendor-sponsored giveaways, limited edition drops. The result: if you shop strategically, 4/20 is the best single day of the year to stock up.

The typical 4/20 promotion structure across legal markets falls into a few categories: **Store-wide percentage discounts.** Most dispensaries run at least 20% off everything. Many go to 30% or 40% for the day. Some split it by category — higher discounts on flower and pre-rolls, slightly lower on edibles and concentrates. **Brand-specific BOGOs.** Cannabis brands coordinate with dispensaries on "buy one get one" or "buy two get one free" promotions, usually on their fastest-moving SKUs. These are often the deepest value but tend to sell out fastest. **Tiered spending discounts.** Spend $50 get $10 off, spend $100 get $25 off, spend $200 get $60 off. These reward stocking up. If you were going to buy flower anyway, hitting the next tier usually pays for itself. **Limited drops and exclusives.** Some brands release 4/20-exclusive strains, merch bundles, or glassware. If you're a fan of a specific brand, check their social channels the week before 4/20 to see what they're dropping. **First-time customer stacks.** Many dispensaries let you stack their first-time customer discount (often 20-25% off) with their 4/20 sale. If you've been meaning to try a new dispensary, 4/20 is the day. To compare actual live pricing across dispensaries near you, browse 4/20 deals on CannMenus. Prices update throughout the day from each store's point-of-sale system, so what you see is what you pay.

4/20 is chaotic at most dispensaries. Lines can be 30-60 minutes at peak times (4:00-5:00pm is the worst). Popular products sell out. Some dispensaries change their hours. Here's how to avoid the worst of it. **Go early or go late.** Most dispensaries open on 4/20. Being there when they unlock the doors means shortest line, full inventory, and calm staff. Late afternoon (6pm-close) is the second-best window — the rush is over, but many deals still run. **Pre-order if your store allows it.** Many dispensaries offer pre-order through their own site, Dutchie, Weedmaps, or Jane. Place the order the morning of 4/20 before you leave the house, then skip the main line when you arrive. This alone can save you 45+ minutes. **Have your payment ready.** Cash is king at most dispensaries (federal banking restrictions), but debit via PIN or POS apps like Dutchie Pay is common. Check your store's payment methods in advance so you're not stuck at the counter. **Know the purchase limit.** Every legal state caps how much cannabis you can buy in a single transaction. In most adult-use markets, it's 1 ounce of flower or equivalent. Don't show up planning to buy two ounces — you'll either get declined or have to split transactions. **Check the menu before you drive.** Menus shift rapidly on 4/20 as products sell out. A product listed at 10am may be gone by noon. Use CannMenus or the dispensary's own menu to confirm availability before committing to a specific store.

Not everything needs to be purchased on 4/20 — but some categories deliver outsized value when you buy them during the holiday. Here's where the 4/20 discount compounds. **Flower.** Eighths and quarters are where most stores run the deepest discounts. If you burn through flower regularly, 4/20 is the day to buy bulk. Well-stored flower (sealed, cool, dark) lasts 6 months easily. **Pre-rolls.** Especially infused pre-rolls and multi-packs. Pre-rolls have short shelf life appeal (most people smoke them within a few months) but they're one of the heaviest-discounted categories on 4/20 because vendors push hard for placement on the holiday. **Concentrates and dabs.** Live rosin, hash rosin, and badder often see 25-35% off on 4/20. Concentrates have excellent shelf life if refrigerated, so buying extra is low-risk. **Cartridges.** Distillate carts go deep on 4/20 discount. If you use a cart daily, buying 4-5 at once on 4/20 can save $50-80 versus buying them one at a time over the next few months. **Edibles.** Gummies, chocolates, and infused beverages often see bundle pricing. Edibles typically have 6-12 month shelf life — easy to buy ahead. **Skip on 4/20:** One-off novelty items (seasonal merch, signed glassware), random low-volume products you're curious about (you'll probably try them once and forget), and anything that requires fresh-dated batches like live rosin if it won't be stored properly. You can browse what's in stock on CannMenus filtered by category and price to plan your shopping list before the day.

The challenge with 4/20 isn't finding deals — it's finding the best deals among the sea of marketing. Every dispensary claims they have the best 4/20 sale. The only way to know is to compare actual prices. CannMenus tracks real menu pricing from thousands of dispensaries. For 4/20 specifically: - Use the 4/20 deals page to see highlighted deals from dispensaries across the country. - Use dispensaries near me to sort by distance so you're not driving across town for marginal savings. - Use search to compare a specific product across every dispensary that carries it — this is how you find the lowest price on your favorite brand without checking five different store websites. On 4/20 itself, menus will update faster than usual as products sell out and new deals activate. Check CannMenus before you leave the house, confirm your product is still in stock, and if possible, call the dispensary or place a pre-order to lock it in. Most importantly: plan, then execute. 4/20 is a great shopping day — but only if you arrive with a list. Wandering in hoping to find deals is how you walk out with too much of something you didn't really need. Look up what you actually use, find the best price near you, and buy accordingly.
