The Lewisporte store is a small one, in a rather old building located on Main Street in the "big box" zone of the town. The store is somewhat messy, the signage is VERY old and there isn't much room to get around inside there but staff is usually friendly - it has a small town feel and nobody hesitates to help you wherever they can.
They even recommended a few different places in town that I could get what I wanted when it wasn't in stock there! I'm not familiar with Lewisporte, so their advice was quite helpful when I was there for a few weeks.
