Due to a lack of fresh produce, Aldi has joined other supermarkets in limiting the sales of some fruits and vegetables.
Three peppers, cucumbers, and tomatoes are the maximum allowed per customer, according to the discount retailer.
It comes after similar actions by Morrisons and Asda, and experts have warned that the shortages could last for several weeks.
Tesco, Sainsbury's, Lidl, Waitrose, and Marks & Spencer have not, however, made any limitations known.
In recent days, images of empty supermarket shelves have been making the rounds on social media.
Extreme weather in Spain and north Africa, where harvests were hampered by floods, snow, and hail, is largely to blame for the shortages.
At this time of year, a sizable portion of the fruit and vegetables consumed in the UK originate there.
According to the BRC, the produce shortages should only last "a few weeks" before the UK growing season starts and stores find alternate sources of produce.
The restrictions on fresh produce, according to an Aldi spokesman, were implemented to "ensure that as many customers as possible can buy what they need.".
The restrictions at Asda are stricter; each customer is only allowed three lettuce, salad bags, broccoli, cauliflower, and raspberry punnets, in addition to three tomatoes, peppers, and cucumbers.
Cucumber, tomato, lettuce, and pepper sales are restricted to two per customer, according to Morrisons.
