Watch out with ThredUp's checkout. The promo code box is hidden under 'Apply Promo' during the final review, and it loves to drop off if you modify your cart. Also, their big new-user codes almost never stack with bundled shipping or marked-down final sale items, so double-check the math before paying.

ThredUp’s sales are totally random, but banner codes like 40% off drop most weekends. The catch is the 4-hour cart timer. Cart what you want immediately to lock it down before someone snags it, then check out. Also, utilize the bundle shipping window to combine orders and dodge multiple shipping fees.

You have to verify through ID.me on thredUP to grab the 20% healthcare discount. Heads up though: it won’t stack with their site promos. Honestly, their regular clearance sales often hit 30% to 50% off anyway, so check the promo banner first. If there's no better sale active, definitely use the code.

Yeah, thredUP doesn’t have a points program, which is annoying. Nobody really pays full listing price anyway, though. Most people just rotate fresh burner emails for the 40% new-customer codes. Also, make sure you use their 7-day bundle window at checkout so you don't get wrecked by separate shipping fees.
