I dont like using amazon but they’re often the cheapest for the things I need. Thats benefited me, but also disturbs me as you watch high street retailers die off. I tend to screengrab products so I can come back and compare prices later. Some of the sales prices are bogus, they’ll jack the price up a week before, reduce it again for the “sale” and put “35% off!!!” You’ve really got to keep on top of it and be vigilant.
