Saw this banner in store. Only valid till 22 Jan 2023 so you still have one day to collect it.
If you are a teacher, administrator or school staff you can get a free goodie bag which include a bag, some lollies, pens and a lunch container. See this pic
Available to new and existing Costco members, you need to bring valid school/employment ID to collect it.
Seems like its running in the following locations based on the banner:
Docklands
Epping
Ringwood
Moorabbin
Visit the membership counter to receive your exclusive goodie bag.
Also available at Auburn, NSW. There isn’t an advert at the store but I got one at the counter (they had a shelf of brown paper bags behind the counter).
