A decade ago, I remember the experience from Monoprice being very fast. 1-2 days between ordering and having it delivered from Rancho Cucamonga to the Bay Area.

But earlier this month, I ordered something from them and it took 4 days to hand it off to some shipping company, 3 days for that company to deliver it to USPS, and another 2 days to get to my door.

Good if you need a lot of cables, if you just need one or two then amazon is still cheaper and you get it faster.
