I have been a customer at Per Supplies Plus for years. My cat recently died and I brought an unopened pack of Breeze litter pads to return. I have a rewards account and used a credit card but they would t take it back without a receipt. It is possible to return without a receipt - many businesses do it but not Pet Supplies Plus. They gave me a gift card even though I have no other pets besides my cat that just died. This practice just highlights how they want to get every last dollar possible from people - really a shameful practice. If I ever get another pet I will not be shopping at Pet Supplies Plus, nor would I recommend it to anyone.
