The biggest challenge to Bitcoin commerce is the lack of consumer incentive to spend.
Purse generates this incentive in the form of 15% discounts on Amazon. Buyers can purchase bitcoins with a credit card as easily as checking out on Amazon, thus solving the last mile problem.
ShadowBid is the best way to save money on Amazon! Prices change up to 80 million times every day (shocking!), and we help you take advantage of all that volatility through automated purchasing when the price drops to the level you set. Find your product, view the price history chart, and set your price. We'll take care of the rest for you!
