Daily.

LTJG Miles, I match charge slips with the statement before shredding the slips. They do slip in annual account charges and interest on 'free' cards.

I don't use credit cards. I don't need to because I don't use credit cards. Sounds redundant, but debt service on non-essential consumer debt is in the commonly one of the top three or four obligations of the average American household budget.

Debt free, including any mortgage since 1998.
