Have you tried the Harbor Freight inside track club? What sort of discounts and extras does it give you? For $30 a year, I assume it would pay for itself quickly.
I'm in some club with them but I don't know which one. I pay $30 but honestly I don't use it often. I should probably check to see what I'm missing out on.
Their prices are so low to begin with, I never bothered to look into any kind of savings clubs they may have. I go to Home Depot so much for my lumber needs that it's my go-to for everything else. I seldom do HF anymore. I have a neighbor who has it though and he swears it's the greatest thing since sliced bread.
