Sharing id

With respect, as a matter of law, and the fact remains that this is a matter of contract law, what you have stated is incorrect.

In effecting a contract, there must be a “meeting of the minds,” which means that the terms of the contract are to be mutually understood. Where there are ambiguities in a contract, these ambiguities are to be interpreted against the draftsperson of the contract, per the contra proferentem doctrine.

Perhaps you can assert there was an implied term of the agreement insofar as an ID exchange requirement prior to purchase. However, at least in my experience, this is not a common practice in eBay transactions, and thus an ambiguity to be interpreted against you in interpreting the terms of the contract.

I do not mean to lecture you, and am not providing legal advice, but noting a word of caution regarding the belief that one can alter the terms of a contract after the fact. Once an offer extended has been accepted, you are bound by the terms of that agreement.

Agree re: unlikely repercussion in practice insofar as the eBay transaction. My comment was more in response to OP’s indication that “As in business, diligence doesn’t have to be done 100% before making an offer that is accepted...”

Thanks all - lesson(s) learned. I appreciate the feedback.

P.s. Re comment from Dan S.....in no way am I embarrassed. We all make mistakes and learn from them!

pps turns out seller has a criminal record in the UK....albeit for violence but not for selling fake expensive toys!
