Since there are places where it is advised to avoid using a debit card, often times I will use a credit card. Then my husband and I will buy things separately and I get the credit card bill and am surprised by the balance. Can I get some suggestions about keeping track and paying it off as I go? What is successful for you as a couple? (How does the right hand know what the left hand is doing?) I am not signed up on line right now....I suppose that will be one option.
