Just finding the non-United boards - more power to these guys, I say!
Anyhow, I checked out Goldpoints.com and it seems possible to still get > 450/$ w/out too much hassle.
Hickory Farms gives you 225 points/dollar and has $100 gift certs. If you can resell that for just $50, there's your 450 pts/dollar. Not sure how big the market is for those things, but if you could get $90 for them, you're talking 2250 points/dollar - 500+FF miles/dollar - not bad! I can just imagine the eBay price wars!
All I need to do is find a lot of people who love FF miles and sausage and I'll be able to crush milespy!
