I'm becoming a more and more a supporter of online purchasing. I've always done mail order since I was a kid. Though the "fear" of paying and not getting began dissipating sometime between 1985 and 1995.
Prior to 1985 I was always concerned that I would pay for something and never get it. Mail order was scary! Post 1995 I never thought twice (or even once) about it. Don't know what, or if there was, any once experience in the intervening decade that changed my mind.
Well there was that whole "allow 4-6 weeks for handling" that was common in the 70s and 80s
