What is a good retail price for the flashing blinky lights?
The best way to maximize revenue is to sell them 1 for $6 and 2 for $10. Most customers will hand you a ten-dollar bill and get two. Some people sell them for up to $8 each and some sell them cheap – 1 for $3 and 2 for $5. At any of these prices, there is good profit to be made. For larger/more expensive items increase prices accordingly.
