Let's get a list together, I will update the post as you list them!
Kohls: If I find the same item with a lower price at another store, will you match/beat the competitor's price?Yes! We do match our competitors' prices. Just bring a copy of the competitor's ad with the current date on it to your nearest Kohl's Department Store. (Make sure the ad includes a description of the item.) This applies to in-store prices and products only, not to Kohls.com pricing or products.
Bed Bath & Beyond
Never be afraid to ask if a store will price match. You may be surprised! Don't stop at just the cashier- make sure to ask for a manager or a CS rep. Ask the person who has the authority to make an exception if it is not in their normal policy to pm. Make sure to have a copy of the competitors ad, or a print out of the item and price from an online retailer. Some stores prices in store differ from their online prices! Make sure to get the best deal.
Also- many retailers will allow a price adjustment if an item goes on sale for a period of time after you buy it- keep your rcpts handy-in your purse even- in case you run across the item on sale!
