It's sad to say but people who pay off their cards every month don't make a lot of money for the credit card companies. I once had my card cancelled because I never ran a balance. It took many phone calls before the truth finally came out.
Not saying this happened to you dogfish but maybe they are in the works of fading you out.
When this country was built, Sears was an important icon. Many households had a sears catalog being mailed to them regularly. Some of the early houses were supposedly built from Sears kits. When was the last time you bought anything from a Sears catalog? And their customer service it the pits, bottom of the barrel. They are another American company that is using the brand recognition of the past to sucker people into buying the crap they now carry. They are a completely different animal from the old Sears, that's why they're trying to branch out into the credit cards beyond the Sears card. Stick a fork in them they're done.
