They do price match ya know. Take in a flyer, dated of course showing the lower price and they will match it.
I did that with a Lebarons flyer for a bucket of bullets. They matched the price, $10 less from their price, I paid cash and got $6 in crappy tire money too.
Now the Lebaron online flyers don't have a date but if you have a phone that can access web sites, you can pull it up and show them it's current. Now some stores may be more picky and surprisingly enough they don't have computers with web access at the courtesy counter for some reason.
