I have a few GE cards that all saw increases around the same time. Walmart only gave me $100 but I saw anywhere from $300-$400 on the others. No complaints because they were all automatic. I'd axe Walmart if it were not for the free TU Fico score. I just don't use it a lot especially since mom has me as an AU on her Sams Discover.
