I realize there've been a couple group buys/runs on deals/etc., but has anyone seriously shopped these around? I was looking at what Samsung had to offer since I was looking at a second battery for my phone, but they charge full retail, so ixNay that...
Looks like I can get 20,000 mAh for ~$34 -- that's the only number that matters, innit? Well, other than getting a bunch of low ratings for exploding or setting things on fire or leaving scorch marks...
