When I was approved in January I was given $500, but got it increased to 600, used it all on the 6 month plan. 1st month paid 200, second month paid 100, requested CLI and it increased to 2400. paid 100 each the next 2 months, requested a CL of 8k and was given $9600! So it sounds like as long as youre responsible with them they will be very friendly with CLI requests, and considering they are SP, it's worth it to just keep trying!
Sharing some CareCredit Love! I applied for this card today and received a $1500 SL. After reading the comments here, I called the customer service number and asked for a $1000 increase. The rep came back and said congrats I was able to get you to $3234 credit limit. That's an extremely odd credit limit, but I'll take it! Super excited to get my utilization down and this card will do just that!
