Here in the US, it's pretty easy to get a very large limit by paying off significant purchases that were near the credit limit. This is true even when you use balance transfers to other credit cards, as long as you don't let the total balances get too high. I've got one card I've had for about 11 years with a 31,000 limit, and several over 15,000. I probably should be anonymous, to avoid the sights of scammers...
