Walmart online has mismatched the prices on the Cotter Pin Assortment Kits. I bought the 555 piece kit for the price of the 144 piece kit and did an in-store pick up. No Shipping! Only cost me $5.60 these kits normally go for at least double the cost. You have to select the 555 from the drop down menu and you will see the price mistake.
Too bad it wasn't a more lucrative mistake. Harbor Freight charges less but if you don't live near a Harbor Freight store ordering online thru Harbor Freight charges $6.99 to ship + Item cost @ $4.79 = $11.78 . Even if you use the 20% off coupon it still ends up costing a total of $9.42 at HF.
