These stores all seem to be independently owned/managed, so you can't tell by one of them exactly how another will be. But I've been in this Olive store a few times, and I have no big complaints. The owner seems like he's actively trying to locate good prices on items he can order and stock, and you can find a number of older, used parts (Pentium II motherboards and the like) in bins near the back of the store.
I think all of these stores overcharge for computer service, and take too long to get things back to customers ... but that's not uncommon in the business, in general.
PROS: A local way to get some parts you'd otherwise have to buy online.
CONS: They're "hit or miss" on inventory, and repair could be faster.
