The key to the code is not the dollars but the cents. Those last two digits of the price tell you everything. A price ending in .99 is much different than one ending in .97 or .49. Check it out…
Price ending in .99 – the product is full price

Any
time you see the price ending in .99 you know that item is full-priced
and has not been marked down. It still may be a good deal though, this
is Costco after all.
Price ending in .97 – a deal decided by the manager

A
price that ends in .97 is what we are looking for. Usually this is a
special price you’re not going to find again. Once it’s gone it’s gone.
These can be some great deals.
Price ending in .49 or .79 – manufacturer’s special

A
price ending in .49 or .79 is a manufacturer’s special. This is a
product the manufacturer is testing out at Costco, usually at a lower
price than Costco would sell the item at.
Price ending in .00 – the goods are about to go!

A
price ending in .00 is probably the best deal you will find in the
store. It means the manager wants the item out. And once it’s out, the
product is gone for good.
A price tag with an asterisk – it’s discounted and done

Be
on the lookout for price tags with an asterisk. This means the product
is discontinued. A combination of a .97 and an asterisk means you are
getting a last chance good deal.
