Since I cancelled Prime, I have saved a fortune in addition to my $100. Not just on Amazon, but period. Super convenient and fast resulted in me buying more, now I am just buying much less stuff, make fewer orders less often. even waiting to go to a store I figure out a way to solve a problem without buying anything, and sometimes to need goes away.
I guess I have Trump to thank for it, never would have cancelled Prime if it wasn't for the US boycott.
