I've contacted the highest bidder and the domain will be sold within 24-48 hours if I don't receive a better offer. If you want upgrades.net, post your offer here or PM me.
One thing I forgot to mention about the highest offer: it's $2,750 but the thing is, he can't pay everything at once. He wants to send a certain amount now and then continue w/ small monthly payments. The guy is legit but I'd rather sell upgrades.net to someone who can pay me right away. So if you can match his offer and pay now, you'll officially be the highest "bidder". Actually, I'll even accept $2,500 as a better offer if you can send the money now.
