These are the normal price at $2 or free with the Happy Meal but hear me out. From the last deal in the US unopened toy sets are worth for $10USD, Opened Foils for $4-50USD and Non Foils $1USD. I'm not advocating for people to scalp these, I'm using the resale value to demonstrate this is a bargain.

Limit of 2 toys like in the US and UK!
