I got my first spending promo from USB AR ever. $10 off $100 spent at pet stores if done before June 30. They said Petsmart, Petco, and Petsupplies count specifically but other stores would depend on the MCC.
I guess USB is feeling the pain of all the drop in spending and they picked some random category to test out with some demographic. Although they've probably noticed spending on kennels and vets and may have figured they ought to try and capture more wallet share.
