I got a letter telling me they were upgrading my Sears card to a Sears Mastercard in February of this year and am still waiting for the card. The offer was sent to me unsolicited and I use my Sears card for Land's End purchases maybe once a quarter and always pay the balance in full. Because of the Mastercard conversion, I recently requested an increase on my limit from $2,000. I was hoping to take it to $3,500, which is still a low limit, but was told Sears limits the increase to 20% of you current limit, so it's sitting at $2,400. Interested to see what the Mastercard limit is.
