I've spent 3K at tiger in the past two weeks using BTC. I've spent ZERO in fiat over the last decade at tiger. Basically it came down to convenience, I had my cart, hit checkout, was give an address, sent the funds, and got the receipt in my email. It took ONE CLICK from "checkout" to being completely done with tiger's website. Anybody who accepts crypto is getting my business BEFORE their fiat-only competitor from now on.
p.s. If you are "all in" crypto and the USD crashes you're f'd.
I spent nearly $10,000 in BTC at Tigerdirect 2 weeks ago and just like you, I've never spent a dime there in the past. Newegg was always my first stop and then Amazon. And until Newegg and Amazon get on the BTC bus, Tigerdirect is now my electronics store of choice.
I had a peek at Overstock.com too. But what a bunch of crap, lol! I'm not likely to buy anything from them although I would support them if I had absolutely no taste.
