I did get a basically free 20-gauge MEC shotgun reloader from my Cabela's card. That was nice.
I have been able to use them on occasion to help out family. Sister-in-law's car got t-boned by a red-light runner, insurance didn't pay enough for her to get something decent, so I made up the difference for her with one card, about $1500.00. That's all long since paid for. It was nice to use the low-interest balance check that I had received to help get her on her way to and from work and college again.
