Wal-mart pays you $ X.XX for an item, and sells it for $ X.XX. Seems like commerce at it's best.
They don't pay retail for anything. You are basically robbing them of their profit margin. Sounds like theft in my state.
Coupons are like cash to any store that takes them. They are subsequently submitted for credits taking money off the store's bottom line and helps to off-set costs increasing their profit margin.
Those two don't sound the same.
Theft vs. Business.
And if you are caught, depending on the dollar amount (such as your Bond transaction) they are legally able to press charges for petty larceny to larceny dependent upon total value.
