Think about what sort of customers you plan to have. You may thing you don't know where exactly where your fundraising for sports will be conducted, but you can get some idea from what has happened in past years. Does the team tend to sell to their fellow students only, or do they branch out to friends, family, and the local community? Fundraising for sports can be a lot easier if you know what market you're aiming for. Being familiar with that market can help you decide which fundraising programs will work best for your sports team.
How much money do you need to make from your sports fundraising? This can affect what sorts of fundraising for sports you want to do. If you need to raise a significant amount of money, obviously something like lollipops wouldn't work out that well, because you'd have to sell them for months on end to get anywhere. On the other hand, if your fundraising for sports is just going to pay for some incidental things, then lollipops could work for you. Some fundraising for sports activities are suited for larger efforts, and some for smaller. If you have a lot of people on your team, you could go all-out and do something like pretzels, which suit groups with more selling power. Smaller groups, on the other hand, can maximize profits with things like scratch cards or pizza cards.
