Milka and Oreo collaboration* Chocolate with cream and cookie

What is the expiration date of the Milka Oreo Bar 100g (10-pack)?

What are grams of carbohydrates and protein?

Recently had the oreo milka bar and became obsessed. The 300g and 100g packages look different when i view online, are they the same?

Can you ship these chocolate bars with some kind of cooling packs so they dont arrive in liquid form from melting in this summer heat??
