50% of sales per student is set aside
to defray their cost to go to DC.
If your student sells four books at $30 each thats $120 and $60 of that will go towards that individual student's trip total. So it makes a lot of sense to sell, sell, sell!
Your child is definitely welcome to sell more books if they sell out of what they gave. Just come and talk to Mr. Havner about getting more.
NOTE: Other than the above information NO details about the trip/date/etc... have been released yet
