Most people who shop at Aldi will be aware that a lot of the products have a non identical twin. For example, the sliced turkey I normally buy for my son comes with sliced chicken. The pots of joy desserts come with an alternative banana flavour. The problem is that one of the products is always more popular than the other one. In my local Aldi they are only currently selling the least popular of the two on some of their products. So I don’t buy it. I am pretty sure I am not alone. Which means, surely, that they’re losing sales?
