We ran around $50 above our assigned PoE budget assuming payment for all of our stock market and stockroom stock. Only around $250 has been requrested in reimbursements, while the cost outside of that runs to about $13 per team member. It should be noted that items marked with an "*" were obtained for free, and those marked with an "**" were both obtained for free and didn't end up in the final product (prototyping materials.)
