This seems workable for micropayments. A $1 charge would result in $.10 fees. 10% yes, but with something like PayPal the fees would be 33%.

paypal now offer a micro payment service at .11 out of 1.00 for sales under 12 usd its beter than the 2.9% option.

this is good to know - thanks - just wondering whether paypal offers automated sales tax calculations and shipping calc?

This isn't exactly new. What is the new part they are covering in the news?

The one-click pay for of Amazon accounts on 3rd parties is new.
