Gah! Poor Frazer

Frazer (aged 6) saw one of these in Asda and *desperately* wanted it from the moment he saw it.

It's a 'Disney Cars Mega Mack Playtown' Reduced to £25 in Asda, costs £39 most places elsewhere.

I was going to buy and save it for his birthday, but he never even asked me for it - he insisted that he was going to save for it straight away. It's taken him weeks (and us inventing lots of chores to be paid for) but he got there today and bought it.

Half the parts were missing from the box.
It was the last one in Asda.
toysRus and other toys shops around here dont have it.

He was nearly crying when we told him that we had to take it back to the shop, and the dissapointment in his face when toysRus didn't have it either was a killer for me. I bought him a small toy and told him I would order it online but so far it's proven to be awkward. I've just found one in an Argos store, I'm going to reserve it but I've no idea how to get there as it's in east london!
