I am guilty of overspending so bad that we decided to get rid of the credit and debit cards. Now we have a pre-paid card for use on the computer, but other than that it is cash all the way. We have been out of debt 17 years this month. Now that I am legally blind, I can't go to the store by myself, so I do have to have a list, but usually he will allow an extra 'must have' or two.
However, since my wonderful friends on this forum sent me a huge stash, shopping at home is a wonderful adventure. Even my kids will help me find the exact piece I need.
Don't feel too bad, just be honest. Tell him over fresh pie and ice cream and coffee. My hubby would accept a splurge on sale stuff pretty well as long as I was feeding him.
