Supermarket rip-off? Expert explains which products are not worth it. Ron Perduss wants to provide an overview of the supermarket jungle on his TikTok channel.

The journalist and consumer expert not only provides information about current recalls and product tests, but also gives general shopping tips. A sliced ​​watermelon costs five times as much as a whole fruit in some supermarkets. A pineapple can cost up to ten times the price. Some yoghurts or shakes are also labeled “High Protein’, meaning they promise a particularly high amount of protein in their contents.
