Sure. It doesn't really matter where you get your other rat as long as the place is clean and the rats are healthy. Petco gets litters from different breeders so the chance of you getting another rat from the same mom is unlikely.
Like everyone has been saying quarantine the new rat. Good luck with your new addition.
I was just able to put my two girls together. Juliet is a little smaller and she always incites things and then they go into a wrestling match. They get along well. A lot of rough housing though, makes me nervous. But they will calm down some after they are together for a while.
Only problem is, I think my new female might be pregnant. Around me, Petcos only have white feeder rats. I do not like red eyes, they creep me out some. So I go her from Dave's (the only pet store that sells colored rats, all colors). Ahh, lets just say, a lower standard of pet stores. They store the rodents by age and not by sex (They let the rodents breed constantly. And they have tanks of pinkie/fuzzies just starving until they are bought as food. That store angers me so much. When I get my license I am shutting them down for animals cruelty and unsanitary conditions.). So it is very possible to walk home with one rat and end up with ten. As much as I hate them, I love colored rats… So I have to bend and buy from them. But, only rats, no food or anything else.
