There's a right way to shop Everything 420 if you want the deepest discount, and it comes down to timing, stacking, and knowing which offers to reach for.
How to Use the $4.20 Store to Get Free Shipping
Check your subtotal before you pay and, if adding one $4.20 Store item would push it past $15, add it - the order then ships free for the same money the flat rate would have taken.
Everything 420 keeps a permanent $4.20 Store - a collection of items priced at $4.20, filled with grinders, rolling papers, rolling trays, bowls, and lighters. The flat shipping rate charged on orders below the $15 line costs that same $4.20. Spending it on a product that carries your order past the line, instead of on postage, leaves you with something you keep.
Four items from that collection clear $15 on their own, which turns a small restock into a free shipping order. Hawaii, Alaska, Guam, Puerto Rico, the U.S. Virgin Islands, and Armed Forces addresses are rated at checkout instead, so this does not work from those addresses.
Which Mystery Box Should You Buy, and at Which Tier?
Buy the Starter tier of the single category you restock most before moving up, so you learn what the store actually puts in a box before spending more on Lifted or Premium.
Everything 420 sells more than ten Mystery Box categories, each built around one product type - Bong Box, Cartridge Box, Rolling Box, Edibles Box, Bud Box, and Dispo Box among them. The narrow categories are the ones worth buying, because everything inside is something you already use. A general box spreads your money across items you may never open.
Each category comes in Starter, Lifted, and Premium tiers, set by budget rather than by a discount percentage. They are priced as fixed bundles, not as a percent off, so judge one against what the same kind of items cost separately on the site.
Save Your Percentage Code for Glass, Not for Small Accessories
Leave a code unused on any order made up only of papers, lighters, and grinders, and hold it for your next bong, dab rig, or THC device order instead.
A percentage-off code returns far more on a full-size bong, dab rig, or heady glass piece than on a grinder or a pack of papers. Coupono research shows 15% is the most common discount level here, so the same code that trims a small amount off an accessory order takes real money off a large piece of glass.
That makes the order you apply a code to more important than the code itself. Codes here stay valid long enough to plan around, so spending one on a small restock is wasted when a glass purchase is coming. Legal THC devices, carts, and flower also sit above the accessory price range, which makes them the other place a percentage is worth spending.
Which Everything 420 Sale Event Is Actually the Deepest?
Search the 4/20 sale collection for the exact piece you want before deciding to wait until April, and if it is not listed there, plan around the end-of-year holiday sale instead.
The Highest of Holidays sale reaches up to 40% off, deeper than anything else the store runs. The 4/20 sale in April is the better-known event, but its 30% applies only to products inside the 4/20 sale collection, not to the whole site. Coupono tracking data puts the deepest code discount ever recorded here at 30%, so a code will not go deeper than either event.
Black Friday and Cyber Monday land in November, and neither is where the widest discounting shows up - that comes at the end of the year. April carries a second, separate threshold worth planning for: the 4/20 sale adds a gift on orders over $42, which is a different line from the one that unlocks free shipping.
Record a Video the First Time You Use a New Vape or Battery
Open and test every vape, cart, or battery with your phone recording on the day the package arrives, so the footage already exists before the 14-day defect window closes.
A defect claim on electronics at Everything 420 needs a clear video showing the problem, and the window closes 14 days after delivery. Vapes, carts, and batteries are the products most likely to fail, and they are the ones where a photo alone will not support the claim.
Ordinary returns work differently. Unused items go back within 30 days with no restocking fee, but you pay the return shipping yourself. That cost lands on you, so ordering two versions of a piece to compare and sending one back costs you money - pick one and keep it.
