About Thermos

Thermos is the original vacuum flask brand with over 115 years of pioneering insulation technology. The story begins in 1892 when Scottish scientist Sir James Dewar invented the vacuum flask for cryogenics research, creating a double-walled glass container with evacuated air between the walls. German glass blower Reinhold Burger and partner Albert Aschenbrenner commercialised Dewar's invention with a protective metal casing. In 1904, a naming competition produced "Thermos"—derived from the Greek word "thérmē" meaning heat. Thermos GmbH was officially formed in Germany in 1906, and American businessman William B Walker founded The American Thermos Bottle Company in Portland, Maine on January 31, 1907, later establishing a major plant in Norwich, Connecticut. A pivotal moment came in 1978 when Japanese company Nippon Sanso developed the world's first stainless steel vacuum bottle. In 1989, Nippon Sanso acquired Thermos operations in Japan, UK, Canada, and Australia, combining their advanced technology with Thermos's heritage brand. This innovation made vacuum flasks lighter, more durable, and more effective. Today Thermos remains the trusted leader in insulated containers—from travel mugs and vacuum flasks to food jars and lunch systems. The brand became so iconic that "thermos" was declared a generic trademark in the US in 1963. Compare Thermos prices on Grocefully across UK supermarkets.

FAQs

Grocefully is a smart grocery shopping app that automatically compares prices across all major UK supermarkets (Tesco, ASDA, Sainsbury's, Morrisons, etc.) and helps you buy from the cheapest stores. We handle the complexity of split orders so you save money without any extra effort.

Our users save an average of 25-30% on their total grocery bill. For a typical £100 weekly shop, that's £20-25 in savings even after our 5% service fee. The exact amount depends on your shopping habits and the products you buy.

We currently support Tesco, ASDA, Sainsbury's, Morrisons, Waitrose, and Iceland. We're constantly adding new stores and will notify you when more become available.

Grocefully is available wherever the supported supermarkets deliver. Simply enter your postcode when you sign up to check availability in your area.

Our AI scans real-time prices from all supported supermarkets every time you shop. It finds exact matches or suitable alternatives for each item on your list, then automatically selects the cheapest option while considering delivery fees and minimum order requirements.

You can set brand preferences for any item. If you prefer specific brands, Grocefully will only compare prices for those brands. You can also allow substitutions for some items while keeping others fixed.

Grocefully shows you available delivery slots from each store and helps coordinate them. We optimize to get you the most convenient delivery times while maintaining the best prices.

Yes! You can link your loyalty cards from each supermarket and continue earning points on all your purchases. We'll automatically apply any available discounts.

We charge a simple 5% service fee on your total order value. For example, if your groceries cost £100, you'll pay £5 as a service fee. This covers our costs for finding you the best prices, handling multiple orders, and providing customer support.

Our users save an average of 25-30% per shop. Even after the 5% service fee, you're still saving 20-25% on average. For a £100 shop, you'd save £25-30 and pay £5 in fees, netting you £20-25 in savings!

The service fee is automatically calculated and shown before you complete your order. It's added to your total, so you only make one payment. No hidden charges or surprises.

Yes! Grocefully is completely free to download and use. You only pay the 5% service fee when you place an order. Browse, compare prices, and create shopping lists as much as you want without any charges.

No hidden fees! You pay the grocery prices (same as shopping directly), the stores' delivery fees (if any), and our 5% service fee. That's it. We believe in complete transparency.

If you're not happy with your savings, contact our support team. We'll review your order and if we didn't save you money (after accounting for our fee), we'll refund the service fee. Your satisfaction is our priority.

Yes, you can modify orders up until the supermarket's cut-off time (usually a few hours before delivery). Any changes are automatically synced across all your orders.

If an item is out of stock, we'll automatically find the next cheapest option from another store or suggest a suitable replacement. You can set preferences for how you want us to handle substitutions.

Refunds are processed according to each supermarket's policy. If you're not satisfied with your savings, contact our support team - we offer a money-back guarantee on our service fee.
