I am in the Pacific Northwest but we don't have any Harps stores in our area. To compare stores, I start with prices. In most cases you can compare prices on line. Pick a few products that you usually buy to work with. If prices are pretty much the same, then I compare customer service. Ask for assistance in locating an item. Do they jsut point you in a direction or actually help you locate it? If the service is comparable, then I move on to store conditions like: ease of getting in and out of the store and parking lots, cleanliness, organization, etc.
I do not have any Harps. In fact I thought you were going to start a thread about Harps Lager! lol. I know the Harps Lager is good, but I do not know about the grocery store chain.
