You aren't asking the store, you are asking people who have previously visited Petco. So no, I have no Guinea pigs for sale, and you should always call the store that sells live animals to see what is currently stocked. Shipments vary.
As is the answer to 99% of the questions here. You should call the store.
The live animal sales I've seen at Petco are not consistent, and vary depending on what is brought in. Petsmart on Archer Road seems to have a larger variety of live animal sales/adoptions. I'd recommend calling before driving down there, unless you are close by.
