Here's an independent site that reports TeeSpring sales, not some charities that make big sales probably are employing their own publicity engine to drive sales.

Hi,
Teezily could be a very good T-shirt website to help you raise money for Sea Shepherd. It has very low costs and you can design your own shirt in a few seconds.
It's based in Europe and benefits from having low shipping costs for your europeans supporters ;)
The support team is also very good at helping you and giving selling tips.
Just let me know if you have any other questions ;)

If you have some money to start with, you could try printing T-shirts with pictures of whales, dolphins, adorable sea otters, etc. and selling them. You could also try holding an event, for instance a dance or dinner where the proceeds go to Sea Shepherd.
If you don't have a lot of money to start with, what about getting a group of friends together and mowing lawns/shoveling snow, etc. like a regular job, except when looking for customers let them know that the proceeds are going to charity. People like that, and might even be willing to pay more if they're supporting a good cause and getting something out of the bargain.
Good luck!
You can sell with Rada Cutlery for your fundraiser! Rada sells cutlery products, food, cookbooks, and candles, all of which are 100% American-made in Waverly, Iowa. You get to keep 40% of your profit, so a lot of money will go to Sea Shepherd's to help whale and marine life. Rada is easy to work with, and has resources to help you along the way. You should check them out today!
Hope this helps! Good luck!
I have to raise money and promote awareness for Sea Shepherd's... it's a non-profit, marine conservation organization that protects whales and marine life. So how can i raise money, like people in the past have held bake sales, gone door to door, shaved their heads, held basketball tournements...any ideas
