I'm sorry for the late response. One of them has been sold already. I am negotiating with a few people about the other one. The price you fixed is too cheap. I am sorry about that.
There is no problem to wait for the money. How much can you transfer?
I am sorry I could not answer you sooner. The item has already been sold out. I am now negotiating another item with a few people. The price you offered is too cheap. I am sorry.
It is not a problem to wait for your payment. When can you pay?
