It's fast becoming one of the most popular supermarkets in the UK, and it's not hard to understand Aldi's appeal.
Along with its fellow discounter, Lidl, the German chain is now outperforming its "Big Four" competitors, Tesco, Sainsbury's, Morrison's and Asda.
Aldi now sees millions of shoppers come through its doors, attracted by sell-out, pocket-friendly products such as its Big Daddy steak, Hunter's chicken and Dirty Fries .
Its ability to keep prices low is down to a few factors - or tricks - as revealed in Inside Aldi: Britain’s Biggest Budget Supermarket.
The Channel Five documentary aired last night and featured ex-staff and experts who lifted the lid on the clever ploys that the retailer has used to make its products so competitively priced.
One of the secrets revealed showed this is in part down to the size of the check-outs .
As any Aldi shopper knows, these are rather on the small-side.
Experts on the show confirmed that a small till area prompt shoppers to put items straight back into their trolleys and then pack them at the back of the shop.
This means the check-out is cleared quicker for new shoppers, and staff can scan more items.
It's efficiency measures such as these which help keep prices low.
