Exactly, at one point I was shopping various manufacturers for my own venture, China is definitely a huge player, they do make just abut anything dirt cheap. I would not be surprised if they cost even less than that to make over there
SSWC price to produce chargers is probably that or less, I helped fund a young start-up w/ one of those mall kios cell phone accessory carts and the prices he paid for his stuff was super cheap and I'm sure he was paying a mark-up to a distributor.
How about contracts w/ AT&T or other direct sellers of phones? Maybe the Walmart 1st approach will open their doors b/c the phone companies can't have Walmart or others taking from one of their profit centers!
