Hi Rebecca, it definately seems a clever way to get an interest free loan for a time, but I think that unfortunately the banks are cleverer than we are! As you probably know the only reason they offer interest free periods is to win our business and then they want to keep it, not to have us move our accounts around to avoid interest, which is why they stop people reopening them in such a short space of time (unless someone else knows better!). I pay my card off in full each month and recently while shopping around for a better deal I moved from Goldfish to Morgan Stanley which had a better cash back deal. I found out that they would not give me anything more than a �500 limit for the first 6 months. I had �10,000 on my old card and even though I offered to provide my Goldfish statements to prove my limit, they refused to revise it. In annoyance I told them I was going to close the account and I moved back to Goldfish, luckily I had not closed the account at that point!
You may be able to get one to revise the limit for you, if you offer to send previous statements that show you are easily able to pay off a higher limit, but I would not hold your breath as they probably have realised that you are continually moving around in order to try to avoid the interest payments. Best of luck though, oh yes one final word, I have heard that you can get a bad credit rating simply because of opening a lot of new accounts in a short time period.
