Quoted from classiccoinop:If it isn't working 100%, I am confident you understand that we'll need to deduct the non working items from the price.”
If the buyer really said this, it's a huge red flag; that's not how it works. When you bid on an auction, your bid IS the agreed-upon price, based on the description. Now if the machine was listed as 100% working but it turns out this is not true, then the machine was not as described and the buyer has the right to cancel and get a refund, and leave appropriate feedback.
By cancelling, the seller simply saved them both time and money and if the deal had gone through, we would probably be reading the same dueling threads, both complaining about how they were ripped off by the other.
