I haven’t used Amazon in almost a decade now. The biggest tip I have is just avoid Amazon links. I block them from my search results, only go there if I think they might have a part number that I need to reference.
My next step is to reflect on whether I really need the object, and if I really can’t, then I’ll contact the manufacturer directly at their homepage. A couple of times the object has arrived in an amazon box, but I can’t control that.
Finally, I am cool with shipping taking a reasonable amount of time. I would prefer to wait a bit for my object than support the amazon monopoly.
