It happens all the time ! Being a member does not guarantee you have priority before the hundreds of thousands other members....
If you see something you like at Costco, get it because the item might not be restocked.
Someone told me to look for an asteroid on the large white price tag on the shelf, it means not planning to restock.
Call in or talk to one of their customer service rep. if in doubt.
I saw a real nice merino wool sweater sometime before Christmas , thought about it to replace my old worn out one at home ( 3 + years ), did not get it because it's $99. Turned around the following week, all gone.
