My DS (12) wanted a WII last year for christmas. We told him how they were to hard to come by. I pointed out everything we saw in the paper and online about how hard they were to get. I really didn't want him to have his heart set one it. Santa is good...but even he (she) can't get everything!
We ended up finding a web site, that kept track of all the online stores and posted when WII's were available. My DH actually purchased one online, a few weeks before Christmas. Boy, was my son surprised!!
