The next time you’re in Home Depot’s clearance section, look for a price tag that ends in three cents. For example, $66.03. According to Dad Deals, price tags that end in three cents are the lowest the price will go. Often, shoppers can save 70% to 75% off the original price that way.

What if the price tag ends in zeros, like $20.00? Dad Deals said this indicates the clearance item is brand new to the rack. Let it linger there for a while, as it will become cheaper over time. These items will then phase into ending in six cents, such as $6.86, which indicates the item is 25% to 50% off the normal price. Eventually, the sale item will end in three cents, indicating the final clearance and best possible pricing.

How about price tags ending in 88 cents, like $14.88? These indicate special buys. Meanwhile, price tags that end in 97 or 98 cents are regular Home Depot prices.
