Well actually that's not exactly what I was saying. I am assuming that Disney DOES NOT allow resales for anything other than cash.
If a seller and buyer wanted to do some type of trade instead, the resale contract must still be written as an all cash deal, just like any resale contract.
The trade would have to be done on the side, privately between the seller and the buyer. Disney would have nothing to do with this, nor would they know about it.
The buyer would pay full price per point (the going resale rate), hopefully getting through ROFR. If it does get through ROFR, then the seller would give the buyer cash back for the difference between the actual selling price-per-point written on the contract, and the verbally agreed upon price-per-point between the seller and the buyer. If the buyer agreed to pay $50 per-point plus rendering services, but paid $85 per point for a 200 point contract to get through ROFR, then the seller would privately refund the difference ($35 per point) to the seller of $7,000.
If Disney exercises ROFR and purchases the contract as it is written, then the buyer would be refunded his/her entire deposit, just like any contract that didn't make it through ROFR.
I hope I explained it better this time.
