As an additional $100, I would definitely do the following:
-Use $36.25 of it to purchase the 125 T-Credit Standing Order
-Use $44 to purchase an S-Builder Co-op for 2 months
-Use $10 to buy a gift certificate so that I can help my team members buy the WAVE 3 membership.
-Use $10 to buy some PSAs for my team to continue SFI growth.
You can do so many things with $100. Anything is possible. I hope this helps you. Good luck.
