The total went down because some people decided to either pay at Nationals or send money through mail (since they didn't want to verify their account or because they could only pay with a CC, and neither are accepted).
As far as losing money, to be honest, I am not worried. If I end up losing money, that isn't a big deal. If I end up gaining money, that would be very helpful in paying expenses, as I have invested several hundred dollars into the site. If there is enough of a gain, I will purchase more puzzles, and will give some away in a contest, instead of a raffle. I paid a little over $90 for the cube (shipping is quite expensive, luckily I split the cost along with my other cubes from the order), and to ship the cube to the winner will cost about $10. So total, it will cost around $100 for the contest.
The idea of this contest is to make someone happy with winning a 7x7, promote the 7x7 and other V-cubes, and promote speedsolving.com. I hope I can achieve all of these. There is still a lot of time left in the raffle. Only 11 people have donated so far, out of 1700+ members.
