Congrats! Yes definitely make that call to Credit Solutions! It's a great card.
Congrats on the Ebates approval! 3k approval is is a very good initial SL on that. Mine was 1.8k and I was able to bump it to 8k at activation and just took it to 20k last night with no counter. What is your TU currently sitting at? That's what's going to help determine what you can bump it to when you call.
