I can’t think of a time in like 20 years that they actually had the thing that I went there to buy.
Like a few folks have mentioned, I bought my last two TVs there. If it sucks or it's a bad panel or I just don't like it, I just box it up and take it back to the store. No wondering if it'll get damaged in shipment or ganked off the porch (or take a day off and hope it's delivered when it's supposed to be).
They're also really good with getting in amiibo, but that's a super niche thing.
