Aldi shoppers can potentially save money by looking for a 'D' on price tags, a tip shared by Jordon Cox, known as Britain's Coupon King. This letter, located in the top right corner of price labels, indicates that an item is being discontinued and will not be restocked. Shoppers are encouraged to stock up on these items while they are still available, particularly on Specialbuys and other limited-time offerings. Jordon emphasized that this knowledge can help customers avoid paying higher prices at other stores once the Aldi stock runs out. Many viewers of Jordon's video expressed gratitude for this information, wishing they had known sooner to stock up on their favorite items. However, some commenters noted that the 'D' does not always mean a permanent discontinuation; seasonal items may return, and some products might be temporarily discontinued for repackaging. Being aware of this code can help shoppers make informed decisions about when to buy in bulk and ensure they don’t miss out on their favorite products.
