What are the items you put inside a party bag without costing a bomb? I am planning a birthday party for 40 kids in pre school. Appreciate your input.

I think best is to hop to a stationary shop and check out as there are number of such beautiful and utility items for kids that you will love it. You can put right from erasers, pencils, sharpness, stickers, crazy balls, books, colouring books, clay dough, building blocks, water bottle, tiffins, crayons etc., in the party bag. http://www.partycity.com/category/birthday+parties/birthday+favors.do
