Why do grocery stores in the U.S. offer cash back so eagerly?
Cash back from credit cards is handled separately than the rest of the purchase, i.e. interest begins accumulating on that day, and likely at a higher rate, and usually comes out of a lower limit than the credit allotted to that card. Given all these differences, and the obvious revenue-generation situation for the lender, it makes sense for them to give the store an incentive, rather than penalize them further, for the use of such a feature.  Note: I am not privy to the inner-workings or agreements between large stores and credit lenders, so I cannot guarantee any of this.
