To earn rewards at Tesco, customers with a Clubcard can collect points every time they shop.
But now the chain has made changes to its loyalty scheme so it'll be different in the new year.
Tesco's partnership with International Airlines Group and its Avios rewards are coming to an end.
Currently, the offer means £2.50 worth of Clubcard points can be swapped for 600 Avios vouchers.
However, the partnership is set to end on January 18, 2021, and Tesco shoppers can use their points until this date next year.
And any points already collected will stay in the British Airways Executive Club account for three years.
A spokesperson said: "Clubcard is how customers get the best value from shopping with Tesco.
"From Clubcard points that are worth more than any other supermarket loyalty scheme and vouchers that are worth up to three times more than their face value at over 100 Reward Partners, to Clubcard Prices on hundreds of products online and in-store.
"Clubcard customers will still be able to convert points into Avios up until British Airways leaves the scheme in January next year."
The Clubcard scheme works to allow shoppers to collect points whenever they make a purchase in store.
Customers earn 1 Clubcard point for every £1 spent in stores, and for every £2 spent on fuel.
And you've collected 150 points, these can be exchanged for £1.50 worth of vouchers which can be used in a number of places.
The vouchers can also be used for money off meals in restaurants and days out.
