I put items in my amazon cart and the prices went up - any chance they will go back down before Christmas?

I just put this stuff in there at like 11:00, and at 2:15, I noticed my total went up by $30 because they changed the prices! I was burning up mad!! Especially mad, because the only reason I didn’t just go straight to buying them is because I noticed a promotion, where I could get another thing for free, and I was wandering around amazon trying to find the right thing. Well apparently, that promotion also ended at 2:00, so now I’m mad as hell that my total went up so much AND i have no free thing, all because they TOLD me i could have a free thing. ughh, and I don’t want to buy this junk at all, but it’s what my mom wants, and I know she just has to have this one, so should I just go ahead and buy them now before the price goes up again? Or is there any chance it’ll go down if I wait? Thanks!!
