#1 Applied 9/29/11, instant approval $7500 CL. Minimal use initially, then received 15k bonus for $1250 x 3 month spend.
#2 Applied 4/20/12,
they called
me 
and asked if I wanted a second card, said I wanted to segregate expenses, 5 minute phone call, approved $9400 CL. Minimal spend, then received 15 bonus for $750 x 3 month spend.
Have received 10k annual bonus for #1. Am considering cancelling #1 and applying for #3. Or . . . just applying for #3 without cancelling.
