So it seems that Sears, like Wells Fargo marks a payment as 30 days late if you pay after the next statment date regardless of the humber of days it is actually late. This happend to me 4 years ago and when I called about it, they told me that was there policy and it been on my CR ever since.
For 30 days late, I would probably leave it be and put the Sears card in the sock drawer. I never want to have to find out what a company's 30 date late policy. As I found out to my sorrow, late is late.
