Teespring is an awesome service that is changing the way such things operate. Offering a service that allows you to design a tee shirt (with no upfront costs) and then offer it for sale online allows participants to select only the size(s) and/or quantities they want or need. That means a more streamlined process for you, as only the exact number of shirts requested by buyers will be ordered, at the sizes that are needed. Adding to the allure, Teespring claims a high quality product and offers to deliver directly to the recipient, if desired.
Teespring is excellent for fundraising, campaigning, and the like. The process is extremely simple, being done entirely online. You upload your custom design or create one with the Teespring tools. You create a price, provide the backstory of a cause/explain the campaign, and you set your trackable campaign goals (viewable by anyone visiting your website). An URL will be created for you where people can purchase the shirt you designed. Of course you can add the URL to Twitter, Facebook, your Etsy shop, blog, or any other place you would like to advertise and/or sell.
I love the idea of this service for school fundraisers, campaigns, and issues of particular instance that might arise where fast funding is needed (medical instantly comes to mind). It eliminates the need for face-to-face selling, saves you a bundle of time, cuts costs considerably, and aids in tracking procedures. It also allows for the utmost in convenience for both you and those who will opt in to buy and/or otherwise participate. When it comes time to raise money at one of the kids' schools (and I'm sure the time will arise), I will be keeping Teespring in mind.
