Beware of scammer claiming to being able to sell you dream’s NFTs, especially on gumroad.
As of today, NFTs are bought/sold/exchanged on venly market. (After initial offering from the store)
Ofc you can communicate with members on on the forum in regards to the exchange of goods but you MUST transfer the NFT to the other user wallet (on venly)
As far as I know this isn’t possible on gumroad.
(Dont let your ego believe you found a work around for such a powerful field)
