I called capital one about doing close to 4k in balance transfers. They input my request. I currently have a 5k limit and my balance was close to the limit. The system after a couple of days declined it saying i had insufficient available credit. But the weird thing is that they called me today saying they were raising my limit +5k and that the balance transfers would be approved. Is that weird or what. I remember someone posting that if you had a platinum card (and I do) that a 5k balance transfer could equal a 5k increase. I'm going to save a boat load of money on interest because i was paying 15-18.9 on the cards I was wanting to be paid off. Capital one rocks in my opinion. They work hard to please their customer. So now I'll have a 10k limit. Cool!!
