Compare rates across Rakuten, TopCashback, RebatesMe, and Mr Rebates to get the most back at Theory.
The best current rate for Theory is 6%, through TopCashback. Rates often jump during seasonal sales, so if your purchase isn't urgent it can pay to wait for a promo window. As with any cash back purchase, avoid coupon sites that aren't on this list - stacking an unrelated code can sometimes void tracking.
Start at TopCashback's 6% link above rather than going to Theory directly. From there, shop as usual and the order tracks on its own.
Right now it's TopCashback at 6%. Rates move often though, which is why we track 4 providers for Theory instead of just one.
Both spellings mean the same thing. We write it as "cash back" (two words) throughout this Theory comparison, but you'll often see "cashback" (one word) used interchangeably elsewhere - so search however feels natural to you.
