If you shopped at Harbor Freight Tools in the past six years, you could be eligible for some serious rebates. In fact, almost anyone who made a purchase from April 8, 2011, to Dec. 15, 2016, is eligible for a rebate.

Itemized receipts with a “YOU SAVED” amount on them are worth 20 percent of the “YOU SAVED” amount in cash or 30 percent of that amount in Harbor Freight Tools store credit.

No receipt? Credit card statements with Harbor Freight Tools purchases are worth money, too. Just send a copy of the statement for a cash rebate worth 10 percent of the entire purchase or 12 percent of the entire purchase in store credit.

The company just settled a class-action lawsuit that charged the retailer with misstating the discounts it offered by misstating “regular” prices (the pre-discount prices). While Harbor Freight Tools disputes the claims in the suit, it has agreed to the settlement, and even without a credit card statement or a receipt, you may be eligible for a $10 Harbor Freight Tools gift card.

Don't leave this task to do "one day." Harbor Freight is only accepting rebate requests through Aug. 7. Full terms and conditions are here.
