1 box $43 total. 2 boxes $165 total?! Wtf?

Know what you're getting into. If you know, then you'll have a good time.
Some of this stuff is poorly packaged from China. It is likely a knockoff product in that case, and will probably not be the best quality. So keep that in mind.
Memory, blank media, cables, even helicopters? All great experiences so far.
Iphone cases? Sort of cheap, but the cost is so low on some of them, who cares?
I've Never had anything odd come from california. So if it's coming from the states, then don't worry. If it's shipping international, just beware it May or may not be such a great deal.
Oh, I got some questionable toner from them for crazy cheap too and it turned out great.

Also great for funny stocking stuffers. Expect half of them to be iffy though.

You won't find a better deal on cables. Yes, you will find cheaper prices here and there, but not by much. But with monoprice you know you will be getting a quality cable. The attention to detail is even noticeable in packaging. Connectors are carefully wrapped. Cables are wrapped in a circled and not end to end in most cases.
I've also got cord wraps from them and they were nice.
I also was happy with my TV mount. Not Thrilled, but happy for sure. The packaging on that was a bit weaker than some of their other products, but you actually couldn't beat the price for such a long arm. It is very stable, and is holding a pretty heavy older 42" panasonic plasma. Not one of these uber-thin newer displays.

Monoprice = low price + quality cables and mounts

I've sold many games here. It is Extremely simple. You might get slightly more elsewhere for some of the lower priced games, but this makes it incredibly easy. I've sold about $70 worth of games that were only worth 2-10 dollars each. Gamestop wouldn't take Any of them.

I recently had an issue that was actually my fault for not paying too much attention. I preordered a game that came with extra things, but the seller didn't send the code. I wrote glyde and they took care of the issue for me, even though it wasn't Really their problem. That's good customer service. I will continue to use them.
