My spouse works for Costco. Slight addition/correction to Sandy's post:
Costco items marked with an asterisk on the price card are considered "Pending Delete." This means that exact item won't be back, but it frequently means the item will be back in different packaging, or somehow changed from the current version. This is particularly common with food items. So it could be back in a new size, or as a multi-pack, or something. And if it's especially popular, it may be back as a "Kirkland Signature" store brand. In Costco's effort to provide the best pricing on their products, they will often buy out the small manufacturing company, and release the product again under their own brand name. It's another way they can control the quality of the item.
Seasonal items are marked down early (the .97 cents on the price tag) to move them specifically so they WON'T be around after the holiday they're meant to satisfy. This is often because something else is on the way in, and they need the floor space for the new display.
But Sandy's point is well taken: If you see it and want it, best get it now, because the next time it probably won't be there. Love Costco's "just in time" inventory model. It keeps me broke, but happy...
