I always have. If that’s the reason, why wouldn’t you? It’s just business. Once, they’ve offered me a potentential promotion or salary increase to try to retain me (but not nearly as much as I got from the new job). I doubled my salary and got my title promoted twice in 2 years by switching employers twice. If I keep it up I’ll be a CEO in no-time, lol.
I usually order form Amazon for convenience, but sometimes use shopping.google.com. I look up every site before ordering though. Some of the sites that show up in the results are sketchy or deceptive. I also sometimes use Ebay if I’m ok with buying something used, or something very cheap of questionable quality (from people who I’m guessing are just resellers of Alibaba crap).
