Although samples may help to increase business, I don't find them to be necessary. Fundraisers for popcorn, candy, wrapping paper even, just have pictures and descriptions. You don't sample the popcorn- you just assume by the description and pictures. If you decide to limit the scents offered, maybe purchase inexpensive small tins/containers that you fill with the scented wax. This would be time consuming on your end and will increase your costs. Good luck!
