Capital One is sneaky. They automatically increased my credit limit by a whopping $500. When I went in (same day I got the alert) and did a Credit Line Increase Request, I got an immediate response that said I could not request an increase because one was recently granted!
I'm like, really?! $500?!
Evidently you need to have 89 or 179 days on your calendar and try and request at 89 or 90 days or 179 or 180 days... before they auto-increase it by a tiny amount. Now I have to wait months again before I can request 3x my current limit.
Ughhhh....
