I'm surprised that you have had bad experiences.

Evil corporation and all that and I am uncomfortable defending it, but I have had a drastically different experience.

I frequently get stuff next day or within 2 days and always get refunds without having to jump through hoops or anything and there are multiple places to choose from for dropping off a return. Also, the price is almost always cheaper or within a dollar of where I can find it elsewhere.

I've had some things take longer to arrive but they are clear about them not being prime and are up front about the delayed arrival time before I submit the order so I know what I'm getting into and if it's something that I need quicker I just pick a different similar product that is prime eligible. There's almost always an alternative that is a similar price with faster shipping. I've never had an order not show up either. In fact, I've never had to even call them or contact support at all.

It's too consistent to be good luck. Hell, it's so convenient that I feel guilty for buying stuff that I could get locally for a comparable price but would require me to fight traffic and stand in line to pay.

Maybe the difference is regional? Or maybe a rural area vs city thing? I don't know. I guess the bright side for you is that you're spreading your money around? Regardless, it sucks that you've had so many issues!
