I have found the Shop for selling merch as a way of fundraising to be very helpful. Its easy to manage inventories, take payments, and stay in communication. The best part is for pre-orders on items. Can set a deadline for when the pre-order closes and take payment. Then its zero risk to place the order. One time events and ticket sells it works well for but creating merch to sell to your groups is a great feature everyone should be using to boost fundraising! Having a landing page with the store on it, and the one time events is a newer awesome feature to combine with this.
