If the label says 4.95 it’s a fraud to not sell it to you for that price.
Within reason and I've seen many disclaimers or fine print that they're "not responsible for obvious errors", but who decides it was obvious or not. In this case, for clearance 5-quart oil, $5/each isn't unheard of but honestly, even $14.95 is still a really good price.Some states have laws that put the onus on the retailer to be vigilant about their price tags -- the price marked must be honored, whether valid or not
I've encountered that before.... More than once, I pull out my phone and place an order for "in-store pick-up". One time, the store employee apologized that they can't honor the online price but told me to order it online ! He waited, his handheld dinged with a new order (mine), and we finished it that way !only to find when you go to buy the item at the store you are told that that is the online price only.
