I haven't gone through the 152 past comments so apologies if this is dupe. but recently I was on amazon to buy something and the original price was like $17 but it tried to snag me by presenting a deal like $12 so I added it to my cart. I think I might have misread the countdown clock which appeared to be like 5hours (maybe it was 5 min??). but later when I returned to the cart (less than 5 hours later but more than 5 min later), I had a note saying I had less than 2 min to make the purchase) which I thought I completed in time but was charged full price regardless. maybe this is a new feature(?) and buggy but I thought it was quite misleading and confusing. I still bought the product b/c it was useful to me but the pricing mechanism could have been more transparent.
