Invalid cards, had to call customer service
These cards show invalid when looking at the website. You actually have to call the petco customer service line to see if the cards are activated. I bought 4 of these. All 4 showed invalid cards but when I called, 3 of them actually did have the correct balance. The 4th one though was an invalid card. Amazon did replace immediately. Same problem with the replacement card though. Online showed invalid card, had to call customer service at petco, Balance was good.
