We live nearest this Petco but travel to the Petsmart in Irvine because we've noticed this store marks up prices by sometimes $3 or $4! We buy a certain brand of cat litter (priced by Petsmart @ 8.99) it is $13.99 at this Petco!! When I mentioned it, they didn't seem to care, so I left and purchased elsewhere. The only thing we EVER go here for is mice for our snake. Petsmart doesn't carry mice, so we have no choice. Tustin Petco also never has enough people serving customers @ registers. And you can forget about getting assistance for fish or crickets. It is next to impossible.
