If you are looking for a decent price on gas, PDQ in Mound is usually a good deal. Because of competition with a local SA, the prices are usually average or lower. And, for your convenience, there is pay at the pump.
And for some food items, PDQ is the way to go. Our favorite buy is milk (with 2 kids we can get a Gallon every 2-3 days). The price is 10-20 cents cheaper then the local Jubilee.
