The total cost of camp is $450. The first deposit of $150 is due by January 24, 2021 and the final amount of $300 is due by May 16, 2021. ALL MONEY IS NON-REFUNDABLE*. The only case I'm able to refund any money is if another student is able to take the place of student who is dropping out of camp.
If you paid $150 last January 2020, then you only owe $150 by January 24, 2021, and $150 by May 16, 2021.
