Reader Jeff tells us Genuardi’s grocery in South Jersey is running a special now where if you buy three cans of Old El Paso Refried Beans, you get zero for free. Quick, someone post it to Fatwallet. Price tag errors are all around us, and if we look close enough, they’re potentially amusing. Other times, they’re not funny and cost you money. Wait, maybe that’s not a zero. Maybe that’s what your rectal chute looks like after eating three cans of Old El Paso Refried beans. They’re advertising the “unique product benefit.”
