If the gift certificate is enough, I'd get a pair of Ugs from Australia.
In fact, I once got a home equity loan in order to buy a pair. They're the onliest things I wear, in footwear, that is. I never take them off, except in the shower; tub bath, I just leave them on and set my feet atop the spigots.

cat'sfor you. Wakey-wakey.)
