1) Since there are a limited number of shirts funded by sponsors, we can't set aside shirts for donations that may not come in.
2) The Turkey Trot is coordinated by a very small group of volunteers. We've spent too much time in the past, trying to connect with people to get them to send in their donations. We just don't have time to do this, so we implemented the 5 day rule. The easiest solution is to pay immediately using PayPal. If paying by check, 5 days gives you enough time to mail your donation and for us to receive it.
Hope this makes sense to you and we don't seem too harsh.
