Honestly, don't buy their multipacks at full price on the main site. Wait for their semi-annual clearance, or just check Nordstrom Rack or Saks Off 5th where they dump excess stock for cheap. If you do use 2xist.com, spin up a burner email for the 15% pop-up code—it usually stacks on sale items.

Don’t pay full price on 2(X)IST. If you sign up for their newsletter in an incognito tab, you'll get a quick 15% welcome code via email. Honestly though, check Nordstrom Rack first. They regularly dump the 3-packs there for half of what 2(X)IST charges direct, especially once you factor in shipping costs.

Just a heads up on 2(X)IST returns: you have 30 days, but they’re strict about underwear. Packaging has to be completely unopened with tags attached, or they’ll reject it. Go through their online portal to grab a prepaid shipping label, but expect them to deduct a return fee. Watch out for clearance packs, since those are final sale.

Their checkout hard-caps you at one promo code, no stacking allowed. Honestly, their sitewide clearance usually beats the 15% welcome code anyway. If you’re just buying basic multipacks, check Nordstrom Rack or Amazon first. They often price them lower than 2(X)IST’s own site, even after applying a coupon.
