I use E-rewards only for Hilton. They have been sending me quite a few high dollar offers, and I find myself with over $130 after redeeming for $25 FTD certificate. I can redeem for HH again this month, and still, I'm stuck with too many points.

So, unless you think you're going to be ordering flowers, I wouldn't waste my time getting another $100.

I did trade someone the blockbuster certificate here in CC once.
