Why do Aldi and Lidl have such fast checkouts
IF you’ve ever shopped in Aldi or Lidl then you’ll probably have experienced its ultra-fast checkout staff.
Aldi’s speedy reputation is no mistake, in fact, the supermarket claims that its tills are 40 per cent quicker than rivals.
It’s all part of Aldi’s plan to be as efficient as possible - and this, the budget shop claims, helps keep costs low for shoppers.
Efficient barcodes on packaging means staff are able to scan items as quickly as possible, with the majority of products having multiple barcodes to speed up the process.
It also uses “shelf-ready” packaging which keeps costs low when it comes to replenishing stock.
"Goodness thank you I had no idea what this meant on packaging!" another added.
"Oh wooow, what a life hack," a third praised.
"They are called Julian codes," someone else revealed.
"That's why you go for the ones in the back," another wrote.
"Are you sure about this?" someone else asked.
