#3 Store just ASIN and get the rest dynamically

[Jason Levitt]

It would be nice to have the ability to store just an
ASIN and retrieve the rest of the
product data dynamically from Amazon.
This isn't that hard to implement but we'd need the
caching layer (see the caching layer feature request) so
that we don't have to keep going to Amazon all the
time. This feature
would allow admins to potentially get any field they
wanted from
Amazon for their product displays.
