COS FAQs
How do I use my COS coupon?
Tear open the ticket to reveal the code, copy it, then paste it into the “discount code or gift card” box at COS’s checkout and hit apply. That’s it.
How many COS codes are live right now?
There are currently 10 active offers for COS in our ledger, each one checked by a person before it was posted.
Can I stack multiple COS codes at once?
COS allows one code per order, so stacking isn’t possible. Pick the strongest offer — top codes usually apply to sale items too, so you can still layer savings that way.
Why didn’t my code work?
Three usual suspects: the code doesn’t cover the items in your cart, it’s limited to first orders, or it expired since our last check. Try the next ticket on the list — that’s why we keep several.
