I have 2 Advanta cards (2 businesses) I got the one that is 2.99 fixed for life on balance transfer!!
APR for purchases has recently went up on both of them, the big one this month from 17.99 - 34.99. Advanta says they re-rated all there accounts and put new credit risks on them and that I could request a decrease in interest every 3 months.
My other one went from 7.9 - 16.99 and then they lowered it down to 13.99 when requested.
Like I said though I used both accounts as balance transfer so interest rates on purchases did not effect me at all... They give GREAT credit lines and you can request increase based on payment history alone every 6 months. I highly recommend if you need a balance trasfer card or need a high limit purchasing card that you will pay off each month. but for carrying purchasing balances there is much better.
