Most shoppers walk into Costco, grab the giant ketchup, and head for the checkout.
That's fine, but it means they're missing the price tags that actually signal a bargain.
Costco uses a quiet code on its shelf signs, and once you know it, you can tell a real markdown from a price that's about to drop even further.
If a price ends in .97, that item has been marked down by the manager.
It's a deal, but not always the final one.
When you see a price ending in .00 or .88, that's typically a clearance or a last-chance markdown the store wants gone.
A little star in the upper-right corner of the sign means the item won't be restocked.
Combine that star with a .97 or a .00, and you're looking at the store's deepest discount on that product.
Markdowns tend to hit hardest when a season flips.
Patio furniture in late summer, holiday decor in early January, and winter coats in February often get slashed before they vanish.
Costco would rather move them than store them.
The warehouse giant also runs unadvertised deals through its monthly savings book, which you can find online without a membership.
Those instant rebates stack on top of already-low prices, and they change every few weeks.
Furniture, grills, and display electronics sometimes sell at a steep discount if you ask a manager.
They can't sell the display as new, so they'd rather cut a deal than box it up.
Costco's return policy is generous, but it's not a free rental service.
Returning a used item you simply didn't want can get your membership flagged if you make a habit of it.
And don't assume bigger is always cheaper.
Unit pricing is printed on the shelf tag for a reason.
A 40-pack of granola bars can cost more per bar than the 24-pack next to it if one is on markdown and the other isn't.
The other trap is the treasure-hunt layout.
Costco moves high-demand items to the back so you walk past everything else.
Stick to a list, or you'll leave with a kayak and no memory of deciding to buy it.
If you're serious about saving, check the app before you go.
It shows current warehouse prices and lets you scan items as you shop to see the running total.
That small pause at the register adds up over a year.
For families watching grocery bills, the rotisserie chicken, the $1.50 hot dog combo, and the bakery muffins remain some of the best per-serving values in the store.
Those prices have barely budged even as everything else climbed.
None of this requires a coupon binder or a spreadsheet.
It just requires reading the tag instead of trusting the sign.
My take: Costco rewards shoppers who slow down and look at the fine print on the shelf.
The store isn't hiding these deals, but it isn't pointing at them either.
