We asked about this at Member Homecoming when we purchased a block of points at SSR. Because in addition to our OKW 330pts we had two smaller contracts (vb50/bcv100pts) that I've found cumbersome in points management since we don't have enough points to benefit from 11 month home resort booking window, and we often need grand villa accomodations for bringing family so SSR was the perfect solution. But, Disney wasn't buying back or "trading in" -- off the record we were referred to a reseller; but having lurked on these boards for a while I wasn't concerned I knew we'd be able to sell our contracts if we needed to.
