I was very pleased that Migros launched such a program and even hoped that it might be expanded. Now I am disappointed that the items are no longer available or are sold out. What's more, the transparent plastic lids with the light blue rubber seal are no longer transparent after about 100 uses, but are now speckled with white. The plastic is damaged. I've now bought Rotho, so let's see how long it stays "transparent." But back to Mix & Match... is it being discontinued? Lids are no longer available in all sizes, etc.
