I'm new to this game, but I'll chime in:
In the past week, I've been targeted for two offers, one for UA Barclay card (spend 1250/month for 3 months for 15k points) and one for Discover (spend 1500/month for 5 months and get $250). If this is any indication, it looks like we have a busy year ahead of us.
that's junk. never sign up for anything less than 50k points, except for SPG AMEX
