This is a great idea!! I think Amazon is the best place to get a decent computer, but I'm probably a little bias. I shop amazon all the time and am presently searching for a new computer myself. I have seen some really nice ones for as little as $250.00 USD.
I will be making my donation some time on Friday. I have to see what I can buy to help out. It will more than likely be some LEO. I also have some Hivehustler tokens that are just sitting there so I will send most of those.
