These are quite cute but there's 20 to collect this time rather than the usual 16. Of course I need them all 😊 but chances of finding 20 unique bags? I bought 20 from a new box at TRUS today to see what would happen. (Tesco and Argos both had no stock).
So far I have opened 14 of them and to my surprise 13 unique and one duplicate. Not bad going but I bet I won't be as lucky with the remaining 6 bags. Off to eBay perhaps!
Good luck in your hunt.
