I'm using banggood.com site to buy electronic parts for RC hobby for about 2 years, and I could say that it is pretty good site. Prices for goods are the same as in market, or little bit higher, but you're dealing with site, not with seller directly. Support usually responds in 12-24 Hrs, which good. Big plus: Paypal could be used to pay, so you're safe with your shopping.
Also there are a lots of sales/bonus codes, New entonces every month, so you can save some $$$. Only one minus I see: shipping is "free" - it's already included in price, and average delivery time to my city (in Russia) is about 20-30 days.
