I started with an email from them saying I could get 40% off for a repeat order. On their website that became 35% off. In check out it became 5% off! I then got on a chat with them and after 20 minutes of back-and-forth they said they'd give me my 35% off as a one time thing. But when I went to check out, it actually had me making a donation to them as well! This is very disappointing to me because it's easy for me to get my dog food from Petco and now I feel in order to show them that this is not acceptable, I need to change the store I buy from. I decided not to be party to this scam! Be wary of the actual percent off that you get!
