But the real magic happens upon checkout — you don't actually complete your order with Amazon, but place it through Zinc instead. Zinc clones your order through Amazon on your behalf, and you have the choice of how to pay Zinc. Of course your standard credit card is readily accepted, but Zinc will also gladly accept Bitcoin.
Your Amazon order "will be shipped with the speed you originally selected or faster," so as long as Zinc can hold true there, this near-seamlessly turns Amazon into a Bitcoin-friendly superstore.
How do they offer the % discount?
They dont actually always buy from Amazon. They'd just buy the same product from anywhere with better price.
Its like pricecheck bot, but instead of you're doing it manually (checking for the lowest price from various vendors), they do it for you.
I really hope they will succeed. This is a best way to show all those retailers how much more revenue accepting btc can bring.
