Congrats! That's a much better limit, so now you can buy something fun!
Two months ago, I went on a credit card application spree after years of not seeking credit and subsequently rebuilding. The Saks store card was one of the retail I applied for due to my love for fashion plus my good relationship with Capital One. When I applied, it asked me to call a number for verification. Followed the instructions to call, and was approved over the phone with a starting credit limit of $2,250. They pulled Equifax (my highest) that was around 779 at the time. I hope they will increase my limit (I know I can call and ask) to improve overall utilization, so your post gives me hope.
I also applied for the Neiman Marcus card (also C1), and that process was brutal. I was given the same "call this number", but they required me to go in the store to apply hitting me with another inquiry which I plan to dispute. It paid off, though, since they gave me a starting limit credit limit of $6,000 using my Equifax score (again the highest). I hope the limits of these two retail cards increase!
