Frys is our local grocery store here in Arizona.
Frye's Electronics (we have 2 of them) sells just about every brand so it would be tough to know. They discount returns, 2nds, blemished stuff and who knows what else. I have returned stuff there that didnt work and seen it back on the shelf in a few days.
Caveat emptor was invented for places like Fryes. I have bought lots of parts, bits n pieces there but I would be cautious about expensive stuff. Ymmv
