how does return policy work.

If for any reason you are not satisfied with an item purchased from Harbor Freight Tools, you may return the product within 90 days for a full refund or replacement, whichever you prefer. The limited warranty term is 90-day beginning on the date of purchase or order. Bring your receipt the item to return and original payment if credit card or debit card

Some items you might need to pay a restock fee but it works like most other stores.
