We rarely keep money in our wallets. DH's paycheck and my check are both direct deposited and we use our debit cards for everything. A neighbor just came to buy eggs. I only had 3 1/2 dozen to sell him, having sold 5 dozen to another neighbor yesterday and I used up a dozen last night for our supper. The neighbor paid me with a $10 bill. I felt bad, because I didn't have change to give him so I told him to just pay me next time. He insisted I take the $10 and hold the change as credit towards his next purchase. Maybe I should get say $20 in single bills and keep them for change? Or does the credit thing work better? How do you handle making change for your egg customers?
