You guys are crazy. Sure I'll spend some of my $1500 refund, but not specifically for the refund; all that money is is money that you shouldn't have paid in the first place, it's not like a big gift from the government.
Luckily in my case, I didn't really overpay that much, just got tuition credits and whatnot that cut my taxable income quite a bit.
I've gotta get around to opening a money market account, so this will probably be the seed money. And then it will just help defray wedding costs in a year.
