I don't know what America is like. In the UK the Domino's website is very good, very easy to use. Sure you can use BitCoin but I don't understand why someone would want to use BitCoin and pay a premium to do it.
The perfect service for people with bitcoins, who want Pizza, who do not have any cash or any means of converting bitcoins into cash (bank accounts).
I suppose it has a novelty value. Its also a middle finger to anyone you have shown bitcoins to who have said you can't buy anything with them.
At least on the UK version of the website you can pay with cash on arrival. This would remove any credit trial.
Even without a credit trial Dominos would have a record of a pizza being delivered to your address.
If somebody can match your key to your person they can see your entire purchase/sell history.
Which is why keys aren't attached to individuals and can be changed with every transaction.
Yes, some traceability is inherent to blockchain crypto-currencies. But using them anonymously is still easier than with any other electronic payment method.
What you use to pay for the pizza.
Call me when a pizzeria starts actually taking Bitcoins.
Now is that before or after Linux dominates on the desktop and Apple goes into bankruptcy ?
