I personally am not involved in any of the conversations on this post, and i donot sell on RJ, but have bought a few times on here.
My thoughts are if you don't have time to respond to a question/offer to buy or trade and if you sell it, it should be shipped immediately once you have recieved payment. I don't care if you are busy, you had time to advertise the items, you had time to take the buyers money, it's time to take the resposibilty of getting the item to the buyer. There's no excuse to delay a shipment PERIOD.
Be a good buyer/seller and posts like this will not exist, or quit posting to sell on RJ, you donot belong here.
