Simply add the Starter kit to the shopping cart, then add the number of Extra kits you require. There is enough equipment in each Starter Kit for 10 participants, so if you wanted to cater for groups of 15, for example, you would need one Starter kit and one Extra kit. Any questions, please don't hesitate. There are also links below to the 'more information' page and the Starter Kit. Thanks Allen
