Wellllllllll,you could always put one in(as a gift of course)an envelope you auction on ebay.
Or trade it for somthing you could use on the coupon connection
or give it to a friend(I have recieved lots of these from friends who are on the same boat as you)
Or you could use them yourself on your leisure holiday-the $100 ones can make a big dent in your hotel bill,I used 4 on my 8 day stay in Montreal last week-brought the bill down to under $500 usd including taxes and phone calls.
