Until recently I was blissfully ignorant on the subject of gogos. However, my 8 year old daughter was introduced to them by an older friend and now her main goal in life seems to be to collect them all in as short a time as possible. Given that there appear to be relatively few outlets selling these toys (WH Smith and a couple of others), the ability to buy in bulk through Amazon was a Godsend - saved my aching feet! Buying the 10 pack, together with the box of gogos (special collection), has sated her appetite for now at least, though it won't be long until I have to start searching for the next (or previous) series. Still, she does appear to derive a lot of pleasure from playing with them, comparing and swapping her collection with friends and from playing the associated games. Great idea, and the potential for creating more types and series of gogos must be immense.
