Most of us would have had an unexpected item in the bagging area when ordering online from UK supermarkets - sometimes it's logical, sometimes it’s not.

But if you're a Tesco customer there is every chance that you could find an iPhone, a Samsung tablet or a pair of airpods in your next order.

Shoppers this week have been left gobsmacked to find electrical good replacing the products they ordered.

In a statement, Tesco explained: “From [7 April] until 18 April, Tesco Mobile is raiding the nation’s shopping bags to make unbelievable substitutes in luck Tesco.com Click and Collect orders.

“Tesco Mobile’s “Super Subs” has been created to show how amazing things can happen when the worlds of supermarket and mobile come together - all while putting a smile on shopper’s faces.”

‘We ordered apples and got an Apple iPhone’

Shoppers have been sharing their amazing substitutions on Twitter, with one user writing: “A big thanks this week to @tesco & @tescomobile. On Wednesday evening we went to pick up our click and collect order and had a little surprise in there - an Apple iPhone SE. Apparently we ordered apples and randomly got an Apple iPhone! Made my son's week!”

Shoppers that have been given a brand new piece of tech with their groceries receive a card that lets them know they’ve won.

The card says: “You’ve got a super substitute! Amazing things happen when the worlds of supermarket and mobile come together, and so Tesco Mobile is surprising select Tesco.com shoppers by substituting Click and Collect grocery items with a fun Tesco Mobile substitute.

“Nothing makes us happier than putting a smile on customer’s faces, so we’ve put a ‘supersub’ in your shopping to make your food shop even more special.

“Ordered some apples? You might find an Apple iPhone SE in there! Have some laundry tablets in your load? There could be a brand new Samsung Galaxy Tab A7 or that gnocchi you were going to rustle up could be a Nokia, with loads more subs to be found!”
