Today I called in about my NewEgg net 55 account and the nice lady looked over my account and said "I need to transfer you over to verification" so that happened and I was put on the phone with a nice gentleman who verified some of my information, put me on hold for about 2 minutes and came back saying I was approved for a credit line of $1000.00 no PG.
I think having 15+ biz trade-lines so far qualifies you for having been "built". Use those for awhile to build up your score, and show good payment history and then maybe try again in a few months for another. Congrats on your approvals!
