You already know the above-board ways to save money at Home Depot--coupons, price match guarantee, Home Depot credit card.
Despite being a billion-dollar corporation, Home Depot's pricing is surprisingly flexible and can often (but not always) work in the customer's favor. Here are some shrewd ways of securing lower prices at Home Depot.
Negotiate Lower Prices for Less-Than-Perfect Merchandise
Like any store, Home Depot has less-than-perfect items on its shelves. When you see a product that isn't perfect, talk to a store associate about getting a discounted price. It happens more frequently than you can imagine.
Ask for a Price That Makes More Sense Than the Listed Price
Not everything in Home Depot is neatly boxed up and sealed away. Many products are difficult to classify and affix a price to.
If Home Depot Has a Product on Display But Not Available, You May Get a More Expensive Item at the Lower Cost
While this one is not exactly a Home Depot policy, putting a customer first is--so you might be able to leverage it to your advantage. I've done this before, and here's how it works.
Find the 70% Off Bin and Other Shelves with Authentic Bargains
Totally an above-board way of saving money, one that doesn't require any negotiations.
Home Depot's lumber section nearly always has a bin or cart in the farthest, darkest reaches of the store where the lumber is marked down 70%. Much of this is cut lumber that a customer never claimed or miscuts by a Home Depot associate.
Home Depot Karma May Get You--In a Good Way
The one is ethics-dependent and some people may cringe at this. As a life-long shopper at the big orange box, I feel it's part of how our relationship works.
Best advice to prevent Home Depot from overcharging you in the first place: watch the clerk like a hawk; check the receipt after the purchase, and select the "email receipt to me" option so that you will never lose it.
