To buy a gift certificate you
must pay by credit card only,
not Paypal. You will then
receive a code (takes about 24
hours) that you can send as an
email or enclose into a note
or card to give as you please.
To redeem a gift certificate
you must still choose a method
of payment along with, even if
your credit covers the entire
amount (the system doesn't
know that until you click).
