I got lucky as well with 400 in gift cards... bday was last week as well.
I just figured i would buy things I normally wouldn't buy, cuz i am cheap, to make brewing easier... I picked up a nice copper wort chiller, a SS 5 gal pot, and 2nd keg for the fridge. It is supposed to get delivered today so I am excited. Hope you are able to get all you wanted with your GC
Merry Christmas brewers!
