Pie Drives are fab, as are the mango ones and you can do cherries too. Look for things that give you a big profit margin - most of them only give you max 15% of what you sell - some even as low as 10% so it isn't worth the time to organise it. Every year our preschool does a walk-a-thon and an art show and it's money for jam - no outlay so everything is 100% profit. With the walk-a-thon the kids get sponsorship and go for a walk to the park and with the art show, yiou have a day where the parents and grandparents etc are invited for morning tea and an 'art show' of the kids paintings which they do in class anyway - they lap it up and there isn't many paintings left.
