Quoted from fosaisu:but I question how you can be so sure that all MMr buyers have an open-and-shut case for a full refund at this point.
To piggy back on this good point, the problem is not limited to whether someone has a valid cause of action, but what sort of practical recourse is there to that cause of action?
I can say with a reasonable measure of confidence that no attorney (unless it is a close family member doing you a favor) is going to take a case on a contingent basis with $1,000 in damages regardless of the underlying merit.
Some people will respond to that by saying "I'd just take them to small claims court myself" . . . the answer to that is, what if there is a forum selection clause in the contract that says any dispute is heard (through by arbitration or the courts) in Texas or Delaware or California (or Mexico...).
When you talk about legal recourse, nothing is ever easy, nothing is ever simple, and rarely is $1,000 enough to really fight over (there are always exceptions).
