Host a virtual Craft or Vendor Fair on social media. Send out a call to anyone that wants to sell their products or crafts. Have vendors post pictures to an event page with links to purchase. Ask vendors to give a percentage of sales to the American Cancer Society or charge a fee to be included.
Guided Tours / Open House
Collaborate with a local landmark or venue that isn’t normally open to the public and arrange a day for guided tours. Sell tickets in advance. Also offer concessions.
