A while back I applied for a Gap credit card not expecting to be approved, was approved with a $300 credit limit. I had that for about a year and then I asked for a credit limit increase and it was bumped up from $300 to $900. Since being approved initially I have been pretty good with usage and always paid on time. Just about a month ago I got a letter saying I was being upgraded to the Gap Visa card. After receiving the card last weekend I activated it, somewhat excited to have it, during the activation process it asked my income and then told me my new credit limit was $5,500! I was so shocked!
The card is pretty great as long as you don't need to call for customer service because they are all foreign and very hard to understand, with no option for a US agent.
