One of the biggest mistakes newcomers to the retail liquor/wine sales business make is setting up their shop in a highly competitive location. Seeing other liquor stores around an area is kind of double-edged sword. It shows you that plenty of willing customers are around for the stores to be in business, but it also means your store will have less customers as a direct result of the nearby businesses. Take your time to carefully choose a store location in a highly populated area with minimal competition. One or two liquor/wine stores here and there probably isn't going to negatively affect your sales significantly, but there shouldn't be any more than this.
Without the right shelving, your customers won't be able to see all of the liquor/wine products your store has to offer. As a result, you'll lose sales and more importantly - customers. So, what's the best type of shelving to use in a liquor/wine store? Basic gondola shelving seems to be a popular choice. It offers easily adjustable shelves to create a snug fit with the products, it can can be moved around the store, and gondola shelving simply looks nice when set up in a store. Most experienced store owners will agree that there's no better choice than gondola shelving.
You can also save some money by purchasing reconditioned gondola shelving for your liquor/wine store instead of new models. Contrary to what some people may believe, reconditioned gondola shelving looks and functions the same as new ones do. In fact, it's doubtful you could tell the difference when comparing a new and reconditioned gondola side by side.
