Sometimes happens that the article is seasonal and doesn't appear again for months. Costco doesn't sell surplus merchandise, everything they sell is first rate. If you have problems with an item call corporate hq. They are extremely happy to help solve problems.

I believe Costco is approached by suppliers that wish to move their
Merchandise. If the product is popular, Costco will try again to carry the
Product, but the supplier may then decide they don't need to move product
At such a low price and not go back into Costco with their product. So if you can call other Costcos or go on line to Costco.com and see if you
Can get it there. I found certain food products(seasonal) not in my Clackamas store any longer but did find a huge supply in Salem Or, 50 miles away., I purchased enough for a year there. Good Luck

Occasionally, when our local Costco has stopped carrying a particular item, we have put a request in the "suggestion box" that they start carrying it again. Sometimes they will. Otherwise, we go to another Costco which is equidistant from us and they will sometimes be carrying items not available at the other Costco.

Costco items are definitely NOT surplus items. As othes have said, certain items come and go. They are chosen for availability at a certain price, and known quality. Also, each store carries some unique items, tailored to the customer base of that area. A lot of articles have been written about the business model-very customer and employee-friendly... and VERY successful.

Costco does get in special items thru the year. And they have special things that go from store to store. They are pretty study on food items. Frozen food and fruit vegs. But if u do want something and see it buy it. Because it might not be back all year of ever.

Costco is a kind of semi wholesale store. They do replenish items regularly, but then what if someone buys the whole lot to sell it in their retail store? If you need a particular item at regular interval, it's better you make a custom request. They should be able to meet your requirement.

I have absolutely no idea. One thing I learned from experience though is that if you see something you want at Costco, but it THEN, because if you put it off, it might not be there the next time you visit the store. OR, it may not be there ever again. Why? No clue about that either.

I know it can be aggravating, trying to get another of the same item. We have tried to get something as simple as a case of Lipton tea, but were told it's not going to be in stock for awhile. I would suggest trying to voice your concern at the suggestion box, or barring that the store manager.

This can be true. Some items are just their until they are gone. Many items they carry very regularly

It is not a surplus item. Costco carry some great products but if you see what you like buy it then. They will always accept returns if you dont want any.
They rarely repeat the same products to keep customers constantly
Interested so if you see something you really like, get it then.
