Logged onto my Cap One account today to check things out. I have a Secured Platinum I got back in December for $200. A month or so later I got approved for a QS1 and an unsecured Platinum for $500 each, both of which received CLI's of $1000 3 months later via LUV button. A few weeks ago I was able to upgrade the unsecured Platinum to a QS with rewards.
As I'm looking at my accounts today, I notice one card shows $1700 available credit. Did a double take as both my unsecured cards have $1500 limits. After checking the number, I realize they've increased the Secured card limit by $1500! I had no idea they would do this with secured cards! It's a nice surprise for sure.
