We always take into consideration a customers history of buying from us when addressing "BEST OFFER" option. We will respond to you within the allotted time but if it has just been listed we will give it the full time period to allow others to make similar offers or purchase. We list many, many items that may be "One of a kind" or simply "One of a kind on the market". These items usually are placed in collections which are not seen again on the market until once again sold by collectors. If you collect, you realize that is a once in a lifetime occurrence for collectors.....
