I play instant win games as a hobby. I usually win enough prizes and gift cards to cover most of Christmas. Then we also have a savings account that is used for all the holiday dinners and extras that pop up here and there.
A few good sites to win prizes or earn points to trade for pizes are:
Live Search Club
BoomerTowne - The Destination for a Generation
myinstantwin-The most complete listing of instant win games online. Play scratchers, slots, phone in instant win games, contests and more all for cash and prizes
These are all great sites to have fun and save money.
