Harbor Freight prides itself on offering its customers quality tools at the best possible prices. Harbor Freight does not require you to have a club card to get their everyday low prices, but they do ask for your phone number at checkout to match up your purchase with your account. If you have ever shopped at Harbor Freight, you will notice they ask for your phone number at checkout. This helps to keep track of all of your purchases, especially if you need to complete a return. You are not required to give your phone number, but we recommended it for ease of return, should you need to return something.
