1 I have that much business lined up for the next 30 days, I'm not working every day at it. It's more like 10 scattered days of 2-3 hours a day work. I'm relatively new so underpriced to stir up business and rack up positive reviews.

Go to Walmart and take two carts and each one put in same identical items. Go to self check out and pay for each group of items separately, make sure that the final tally is exact for each group of items (ie, you should make 2 purchases of exactly $157.48). Wait a few days then dispute one of the charges with your credit card company, tell them you were double charged. As long as the dollar amount isn't enormous (that'll bring extra scrutiny), they should do a charge back when they see two exact charges within a minute or so of each other. Once you get the charge back, return the items in one of the carts to the store and sell the other items for a 100% profit.

This will likely only work with nominal dollar amounts and if you do it more than once you have to use a different card each time.
