Just bought a carb kit at Autozone. I've already searched all their part numbers to get the best price on the exact same kit (interior packaging has the same part number irrespective of what's printed on the outside box). I buy a kit for $19.99 that is identical to a $24.99 kit.
You have to spend $20 to get a reward credit. I told the girl who was checking me out to get herself a candy bar so the total sale would exceed $20. She picked out a King Size Reeses for $2.29. Brought my total sale to $22.28.
Oh well, I did at least come out $2.71 ahead....
