Several popular retailers use “secret” price codes that can clue you in on whether an item is the best deal at the store or not. Here’s a handy chart you can use while shopping to decode those numbers.
Here are the pricing structures for Costco, Target, Sam’s Club, BJ’s, Home Depot, Gap/Old Navy, Sears, and Office Depot. Look for the price on the tag and if it ends in one of these numbers or letters/symbols, you’ll know if you’re getting a really good deal or just the regular price. (Marked down just means it’s on sale, Final Markdown is the lowest price the store will drop it to, Clearance/Discontinued means the store isn’t gong to restock it.)
If you only remember one thing, though, just look for the price ending in any number other than 9 or 99, and you’ll know you’re getting less than full retail price.
