Honestly, most people who say something like this still return to the store. Ask someone who works the return desk and deals with this day in and day out.
Canadian Tire, Walmart, etc. offer low prices in exchange for lower quality goods with a good return/exchange system. If you choose to deal with an independent store you run the risk of the same quality of goods with the chance of a much poorer return/exchange system. There is the chance that you'll find a good store with high quality goods at a reasonable price, but let's not kid ourselves into thinking that small business owners don't attempt to make every penny they can off the customer.
