Well, my local store sells those things, but they don't push them. Big chains are a lot more all alike than small stores, but they still are IMO strongly influenced by the management and staff they actually have.
I don't worry too much about taking disease home from the birds that are there. 1) they actually consistently appear healthy, I've never seen a bird that appeared ill there 2) Scooter came from a year there very healthy 3) the cages are completely enclosed behind glass walls and you can only make contact with the birds if you get staff to unlock the door that allows access to the back of the cages. I also always wash my hands before I handle my own birds when I've been out anyway.
In addition I don't buy things there that can't be washed unless they are in sealed containers -- I actually worry less about the birds in the store than I do about the people who may have been handling the bird toys. The bird specialty stores I shop at, I'm really just as careful. They typically have birds out and about, plus the people handling the stuff not only have birds at home for sure, but they often bring them to the store with them. I think the potential for contamination there is actually higher, even though they are "better" stores.
