Ok, I figure you ballers know best...
Recently took the Amazon prime trial - mostly for 3d printer filament... Being out in high river - actually works out, as definitely saves shipping and drive to the city costs for the little 1off needs.
But the question is - is there a website that shows you the deals on stuff you're not actually needing but could use up? Price notifications on stuff you're eyeballing etc?
How does one effectively use prime to actually save money on the day to day stuff?
Thanks in advance!
