Pre-sales can work well for a large fundraising team, or groups that don't have a lot of cash to invest upfront. There is no monetary investment required from you with a pre-sale fundraiser - you only have to call up and order it, and then wait for your brochures and order forms to arrive. Then you just conduct a fundraiser as normal, get your orders and your money, and then you gather it all up and send in the amount needed to pay for the products. Sometimes a cancer fundraiser that works on pre-selling will have higher minimum order requirements, and that's what makes those particular ones better for large groups, as they have more selling power and aren't so worried about achieving numbers.
Going with direct sales for a cancer fundraiser means you have to pay for the products at the time you order them, and then we ship them to you to sell directly. A direct sale can include include fundraising candy bars, scratch card fundraisers, or discount cards. These work really well for small groups because the profits are high, and of course there is the benefit that once you have made your initial investment in a cancer fundraiser based on direct sales, all the money you make from it afterwards is yours to donate to the cause. This can work really well if you have the funds available to invest in a cancer fundraiser, and are sure that you will get a good return on your investment.
