Put in your phone number associated with your Pals Rewards Membership at the register, then present the coupon.
I have had two similar offers recently and printed out several copies that I took with me to the store and handed a few out to other people, and they all seemed to work for them, even though it says single-use coupon. Also, it worked on items that had some discount, even though it says for regular priced items only. Good Luck!
Terms:
Present coupon or mobile device and proof of Pals Rewards membership to receive this offer. Valid at Petco or Unleashed by Petco on in-stock, regularly priced products. Not valid on the purchase of gift cards, prior purchases, salon services, dog training, vaccination services, our Self-serve Dog Wash, online or with any other coupon offer. Void if copied, altered, transferred and where prohibited by law. Single-use coupon, limit one per household. Selection varies by store. Valid 8/2-8/3/2019 only.
Edit: I originally posted that this is available only in Maryland, but I contacted Petco this morning and they say it’s available in ALL STATES.
