After buying many things here, I realised that when the price is great, you just got to grab it by paying for it. If I am selling, I would rather sell ASAP to a buyer who wants to pay me ASAP than have one hundred email exchanges on the item.
Calling dibs no longer works and asking questions about condition and fitting etc would only mean another guy would grab it before you. Unless the seller agrees to reserve the items for you, but why would he do that unless you offer a great price?
Not defending yfyf but at least he responded. I can tell you other sellers dont even have the courtesy to reply to say it is sold or pending sale or reserved or not going to sell to you etc.
