This hardware shop, "Let's Do It" is near us here in Podgorica. Not to far from our home in Virginia, there is a hardware store called "Randy's Do It Best." The little smilie in a cap that dots the I is the same. We suspect that the chain name is "Do It" and then individuals can add stuff. For example they could call it "You Can Do It" or "We Help You Do It" or something.
We've looked around in this store, and you can find just about anything in the hardware line you need. They even have WD40! So if we buy that and some duct tape, theoretically we can fix anything!
