sounds like you got a better deal than me
my offer beginning this month for 3 more is if i charge $250; i get 5 X the points...above a threshold of $250 a month (make me an offer I can refuse)

Signed up for it online, don't think i'll bother; always afraid i won't pay it off in a timely manner.
i haven't used it in over a year, not sure if it's designed to get inactive accounts busy? DH has his own account (with a much higher limit, only uses it to run vacation expenditures thru for the rewards) has never gotten an offer over the past few years he's had it.
fyi, they did offer me a low transfer rate @ 3.99% that I utilized.
