As you know (😅), I live near the German supermarket chains. Unfortunately, I can hardly find any limited editions of various brand products in Switzerland... for example, there was white Toffiffee (migros offers this brand). Merci Kokoss chocolate is currently available, but there are also hardly any other summer limited editions here. In Switzerland, there are usually only the best-known varieties and that's it. I think limited editions would also generate some spontaneous sales. You could also supplement the standard range in this way and make the range in smaller Migros more exciting. You do this with Messmer teas, could this also be done in the chocolate range in particular?
