After looking through high school musical things, I decided to look elsewhere as it is quite expensive.  Argos is by far the cheapest with microphones in there for £9.99 compared to some which sell for £16.99 plus postage!! Disney store has cheerleaders outfits for £15.00 as does woolworths! They also have other things on offer, toysrus are also good, aswell as supermarkets for stationary etc.  Just thought I'd write this to save you some money, thanks for reading.
