> I don’t know why any non-Prime customer would want to sign up At least for me, it's easy -- the Prime credit card, which has no extra fee beyond Prime itself. I get 5-7% back, instead of the 1-2% with my other credit cards. It literally pays for itself and more over the course of a year. The faster shipping is just a bonus. And I'm not buying junk I don't need either. It's literally just regular toiletries, my norm…
It’s usually cheaper if you can source it from the manufacturer even paying their shipping rate. In fact the pricing structure on amazon often seems to include this shipping from manufacturer charge in the total cost just you aren’t aware of it. You still get 3% back on that card without prime on amazon fwiw.
This is rarely the case. In fact, it's against Amazon's policies for manufacturer/third-party listings.
But I've found that even when that's the case, returns can be such a gigantic hassle it's not worth it -- getting an RMA, having to pay for return shipping, being forced to use an inconvenient shipping service of their choice, things like 15% restocking fees...
If you're buying something for the first time and then discover it doesn't work the way you expected, it's amazing how much easier and cheaper Amazon returns are.
