Love Costco, but not thermoflask. If you actually care about keeping your food hot, get Thermos Stainless King or the best, Zojirushi Stainless Steel Food Jar.

this is OK price, Costco had High Sierra Insulated Food Jar 2-Pack for %17 when they were on sale.
They were 24oz and also came with steam release function and a spoon.

These are $9.97 in all the stores around me. Picked them up a couple weeks ago. They're discontinued as indicated by the price.
