Update: Looks like this isn’t actually new at all. Read comments for more information.
Chase offers one of the best no balance transfer fee, 0% APR offers on the market. You currently get 15 months of 0% APR on purchases and balance transfers and there is no balance transfer fee during the first 60 days of account opening. Unfortunately they have made some negative changes to the offer, previously you had been able to transfer across up to whatever your credit limit was. This is now restricted to your maximum credit limit or $15,000 whatever is lower. I suspect as interest rates rise the availability of these 0% APR/no BT offers will shrink.
