Like the others have noted, the savings dollars can't be used on most RCI fees. Here's the section on how savings dollars can be used (bolded section is my highlights)
3. Savings Dollars
3.1. Platinum Members will receive Savings Dollars in an amount equal to one Savings Dollar for each dollar paid for the following transactions: RCI Standard Membership Fee Guest Certificate/Guest Pass RCI Platinum Membership Upgrade Fee RCI® Points Partner Reservation RCI Weeks Exchange Trading Power Protection/Points Protection RCI Weeks Combined Deposit RCI Points Exchange RCI Cruise Exchange Weeks Deposit/ Points Extension Points for Deposit RCI®Deposit Restore SM Points Saving Fee
3.2. In order for a Platinum Member to earn Savings Dollars, the applicable Platinum Membership and associated Points Membership or Weeks Membership must be current and paid in full at the time the transaction is processed. Savings Dollars will be posted to the Platinum Member’s Savings Dollar account (provided through a third party vendor) within 15 days after the date the Savings Dollars are earned. In no event may the Savings Dollars on a Platinum Member’s Savings Dollar account earned from this program be paid directly to the Platinum Member in the form of cash, check or credit card, or any other means of payment.
3.3. Savings Dollars may be redeemed as a form of partial payment in a fixed amount at time of checkout on the net amount of products, travel and services purchased through the RCI Platinum Store, including merchandise, vacation packages, hotels, Restaurant.com certificates, Spa Finder certificates and Fandango certificates.
3.4. Savings Dollars will not be earned for any cancelled or voided transactions. Any Savings Dollars credited for transactions which are cancelled or voided will be removed from the applicable Savings Dollar account, or if the Savings Dollars have already been used by the Member toward a transaction, the applicable amount may be placed as a charge on the account.
3.5. Savings Dollars will not be provided for any transaction for which the Platinum Member does not pay the applicable transaction fee (for example, if the fee is waived).
3.6. RCI may, at any time, in its sole discretion, change the types of the transactions for which Savings Dollars are provided, as well as the applicable Savings Dollar amounts (including the minimum and maximum amount of Savings Dollars required for the purchase of a specific product, travel offer or service).
3.7. Savings Dollars and the RCI Platinum store are provided by a third party under contract with RCI. Savings Dollars are subject to additional terms and conditions established by the third party.
