Why does Migros only give you a marble, sticker etc. from 20 sfr? At Coop, you can reach your goal faster with collecting, from 10 sfr you get a collector's stamp etc. It's a pity it's not like that at Migros. Single earning families with children will never achieve a complete collection. The collection campaigns should be family-friendly! It would also be nice to be able to buy missing marbles, glue, etc., like at Migros. It would also be nice to be able to buy missing marbles, glue etc., as with Panini glue.
