Other ways to save at COS

Return in store to avoid fees. Bring eligible online purchases to a COS store to sidestep the mail‑in return label charge and get your refund faster.
Build your order to free shipping. Consolidate purchases to hit the $150 Economy free‑shipping threshold instead of paying separate delivery fees on smaller orders.
Time your purchase for deeper markdowns. End‑of‑season and limited sale events often add extra reductions, and items marked “Final Sale” typically reflect the steepest discounts.
Look for outlet finds. Visit COS outlet locations to score past‑season pieces at lower prices. Note that outlet purchases are usually final sale.
Use cart reminders wisely. Leaving items in your bag can trigger stock alerts or limited‑time offers in follow‑up emails, which can pair nicely with COS coupon codes.
