Using black stretch film to wrap pallets for resale

A 1000' roll is like 30 bucks. Now I can sell a lot of the useless junk, selling pallets today $1280 each minimum of 2. Most are happy with their purchases, one lady complained and I refunded her money minus 10% then cut the wrapping off and sold it right in front of her. It had 5 Yeti coolers that was misprinted.
