We have one person responsible for purchasing. You talk to that person, and decide between the two of you how you want the part ordered.

If the part is ordered on-line, we e-mail that person a link, and the parts person orders it.

Sometimes, after discussion, we go to the hardware store. That can either be the team credit card (for someone over 18), or they submit a receipt for reimbursement.

Sometimes I (mentor) buy (without discussing) some parts (under $25) for something I am wokring on with the team, and submit receipts.

Students should always get permission first. With that permission will come the acquisition method. Mentors have more leaway, but then they also have the financial resources to eat the cost if there is a disagreement.
