I searched for this topic but was surprised it was not previously discussed. Perhaps all you savvy shoppers are already aware of this but I decided to post anyway, just in case. If you’re returning items to AMZ, consider doing so at your nearby Kohl’s because they’ll give you a $5 Kohl’s Cash. The only caveat is it’s in-store use only and expires in a week but not too shabby. If you have another Kohl’s coupon, remember that they take off the $ amount first, then % off. I bought my GC on IB too prematurely, so the total amount was more than expected and ended up paying $1.62 oop for a queen-size mattress topper that was original on sale for $20 - I say it’s a win!
