You are allowed to sell “Experiences” on eBay meaning something like batting practice at yankee stadium
This appears to fall into that category. Its not really a Tzdekah so gofundme really wouldnt work as its not really a charity
I applaud the seller for thinking outside the box, To raise funds you need sometimes to think outside the box
The only issues I see are the following
THE SELLER WILL MAKE EVERY EFFORT TO AMICABLY RESOLVE ALL ISSUES TO THE MUTUAL SATISFACTION OF BOTH PARTIES. ANY OUTSTANDING UNRESOLVED ISSUES WILL BE REFERRED TO ARBITRATION OF THE JEWISH COURT OF LAW CHOSEN BY THE SELLER AT THE TIME OF SALE AND ALL DISPUTES WILL BE GOVERNED BY JEWISH RELIGIOUS TORAH LAW.
This is against ebay rules, anytime there is a dispute with an eBay listing you have to go through eBay for resolution. (Its their platform, they have the right to make any rules they want and if you dont like it, dont list there)
This Is also illegal according to eBay rules, You cannot make an open auction and deny a winning bidder, its against the rules (You can make a Pre-approved buyer auction, which is what the seller should have done)
1) TALMUD SPONSORSHIP IS A PART OF JEWISH RELIGIOUS OBSERVANCE AND THUS UNFORTUNATELY AT THIS TIME BIDDING ON THIS AUCTION IS LIMITED TO THOSE WHO ARE JEWISH BY UNIVERSAL STANDARDS ACCEPTED BY ALL JEWISH COMMUNITIES.
Is also illegal according to eBay rules
