My grandson is 8 years old and loves to collect these cards. It costs his mum and I a fortune but the pleasure he gets collecting and swapping with his friends outweighs the cost to an extent.
Then the adults get involved!
Cards become worth a small fortune way out of the reach of the children they were intended for and parents all over the Country are nagged by their kids in order to complete the sets and line greedy adults pockets!
Give the kids (and parents) a break!!
