Non-Refundable Deposit?

<p>So I applied Early Decision to William and Mary, and I overlooked part of the application stating "Students who are admitted to William & Mary through early decision must confirm their enrollment by making a non-refundable deposit within two weeks of receiving the admission letter. " Does anyone happen to know how much this deposit will be? Is it considered part of tuition costs, and would it be covered under VPEP? Thanks in advance for answers!</p>
