Sears will do it to you even if you still use the card, well CitiBank, that is, and they are not nice about it at all. They decided DH had too much credit, so they lowered it without notice, only when I went to purchase brakes for our van did I find that out, then a few weeks later, they just cancelled it completely, out of the blue and we have been loyal Sears customers for many years.
I won't be shopping there again for a long time, probably never.
I have never had this happen with any other card. WaMu at least sent us a letter telling us that they were closing our accounts for non-use. A short time later, they were bought out by Chase, I believe.
