It looks like everything Thermos Brand is 50% off at Spotlight. I have the food jar and can confirm it's excellent for keeping food hot or cold (they have plain ones, or fire truck or butterfly ones for kids/baby food). There's some nice looking insulted lunch bags, as well as insulated travel mugs and water bottles. Best to check in store for Spotlight as I find their stock checker highly unreliable. I think there's Click and Collect in some VIC stores. Delivery usually kills the deal for cheaper items from Spotlight.
Some examples:
Stainless Steel Food Jar 290ml $15 (this is the one I have and it's great, mixed reviews on some of the others, friends report the kids ones are good too)

Got the Raya Lunch Bag (and another design) last week when it was $18. Had to return it for another as significant freying on the zips, loose threads the whole thing after opening it a couple of times. Was also charged full price when they were clearly marked at 40% off in store and online (Midland WA).
Also be aware online stock levels are not right - was coming up out of stock and they had about 20 of each style in store.
Will be for school - so will see how they go.
