Discount Coupon (in excess of $1.000) to Intensive camp this summer

My son got ill during a high school level intensive camp in a previous year and I have a credit coupon that is transferable but not usable by us (my son is now out of high school) I am not sure if this is an o.k. place to give specific details and to offer to sell it or not. If posting details is not appropriate, please let me know & any suggestions on where it could be posted would be appreciated. thanks.

You must accept Paypal and provide verification from the camp that the voucher is active before the sale can be completed.
