Well, if you can jump on it, it's an awesome deal! I used it to buy Xmas gifts. My grand total is:
6 $25 certificates (1 for each member of DH's family)
2 $50 certificates (1 for each of my sisters and their DHs)
2 $100 certificates (1 for each set of MY parents)
I just got the restaurant.com gift certificates, so everyone can spend them on whatever places they want at the time (as well as buy in whatever denominations they want). It took me a while to make each purchase (3 total), but I finally got it all done! Now I just have to get some nice paper to print them all out on.
Total spent: $22!
