lure purchase

I was at walmart this morning looking at the fishing tackle. I noticed a
desirable more expensive rapala lure priced at a low low price. I selected
three (the other two not marked down) and took them to the register. The other
two scanned at a much higher price (something to do with bar codes). The lad
from sports came to the register and told the cashier to give all three lures
at the lower price to the gentleman since it was a pricing error. It pays to
keep your eyes open and shop at walmart for fishing tackle.
