1ºAlmost no one cares anymore about Prime Day. Most of the “deals” are overpriced junk. If you have had your eye on something essential or of good quality, wait until *after* Prime Day. The discounts will continue or even get better.
I’ve been an Amazon seller for four years. Prime Day brings more customer attention to my shop and a modest increase in sales. I don’t do anything special, like hike up my prices a month before so “discounted” prices look like a deal. As a Prime member, though, the only things I might care about are discounts on items I already had on my wish lists.
