I opened a credit card and it’s 0% for two years on balance transfers. One year down the line that offer finished it was only 90 days. I haven’t put anything else on my card since. A new offer has come up 0% for 15 months but I still have money owed on my credit card. I would like to do another transfer but would that mean the existing offer would stop on the rest of my amoun owed and I start paying interest?! Thanks
