Quick delivery, good bottle

Ordered a stainless steel water bottle. It arrived in 4 days to Bangalore. Bottle is sturdy. Keeps water cold. Good purchase.

Good value for a food jar

I was looking for a good deal on a food jar for my son's lunch. Got the Funtainer food jar with a seasonal clearance offer. Saved a bit, and it keeps his food warm enough till lunchtime. Worth what I paid, for sure.

Hey, thinking of grabbing one of those Thermos food jars for my kid's school lunch. Do these things actually keep food warm till lunchtime? Like, if I pack it at 7 AM, will it still be hot at noon?

C Cober 3 months ago

Yeah, totally. My son has one and his soup is still steaming when he opens it at lunch. Just remember to pre-heat the jar with hot water for a few minutes before you put the food in, makes a big difference.

D Dermistry 3 months ago

They're pretty decent for keeping things warm. I use mine for coffee sometimes and it's good for hours. For food, I'd say maybe 4-5 hours for really hot, then it'll just be warm after that. But definitely good enough for school lunch.

Quick question about placing an order on Thermos.com. I've got a free shipping code from signing up, and I also found a 15% off code. Can I use both of these at checkout?

S Support 2 months ago

Nah, pretty sure you can only use one code per order. The free shipping over $50 usually just happens automatically, so if your order is over that amount, don't worry about a code. Then you can use your 15% off.

G Gabriel Amologu 2 months ago

From what I remember, they only let you punch in one promo code at a time. So you gotta pick which discount you want to use. The free shipping usually just kicks in once you hit the minimum though, so that might not even need a code.
