Sign up to Clubcard
Tesco's flagship loyalty scheme is known as Clubcard, which lets shoppers collect one point (worth 1p) for almost every £1 spent at Tesco as well as offering discounted prices on selected items when you shop.
If you plan to shop at Tesco, even sporadically, you should definitely make signing up to Clubcard your first priority.
You can use the points you rack up to get money off future Tesco shops, or you can use them at selected Tesco partners where they're worth up to three times their face value.
Pay with the right credit card
Tesco Clubcard credit cards are a great way to earn extra Clubcard points wherever you shop.
You'll generally earn one Clubcard point for every £4 spent in Tesco and one point for every £8 spent outside Tesco.
That's not a huge amount, but crucially you'll earn them in addition to your Clubcard loyalty points, meaning you could earn a total of five points for every £4 you spend.
Obviously, make sure you clear your debt in full each month or you'll rack up far more costly interest charges.
Double your points and cut your phone bill
Tesco Clubcard members can use their points to slash their Tesco Mobile phone bill.
If you have 200 Clubcard points, you can double its voucher value to use with Tesco Mobile from £2 to £4.
If you aren't a Tesco Mobile customer, it might be worth considering switching: we recently wrote how it was voted best mobile phone provider in terms of lowest customer complaints.
Below is a handy graph showing the savings you can enjoy (if you spend enough every month).
If you sign up with Tesco Mobile, you can collect one Clubcard point for every £1 you spend on topping up in-store, online or over the phone or for what you rack up on your pay monthly bill.
Fuel your motor
You can collect one Clubcard point for every £2 spent on Tesco Unleaded, Tesco Diesel and Tesco Momentum at selected forecourts.
At Esso petrol stations with a Tesco Express, you'll get one point for every £3 you spend on petrol or diesel.
Please note that you can no longer earn Clubcard points at Esso-branded stations where there is no Tesco Express attached.
If you regularly fill up at such a station and it's impractical to go elsewhere, consider signing up to the Nectar scheme instead. It's now partnered with Esso so you may as well earn loyalty points from someone.
