I'm sure this has been discussed before, but I have no idea where to put it. Mods please move as appropriate!

On the recommendation of my eye doctor, I set off to purchase some lubricating eye drops. Before I left, I checked Amazon. Upshot: the Exact same package, same product, same amount can be bought for $10.90 delivered to my door, or I can drive to a chain supermarket near me and pick it up for a mere $24.99.

Do you frequent the Evil Am-pire? Do you think there's really anything usefully "local" about shopping at a branded supermarket chain that happens to have stix and brix around the corner? I guess I'm helping provide local jobs but it's really hard to see this as reasonable in the face of a 229% mark up from what is already a retail price with some profit built in.
