it's all about your attitude, and/or professionalism. Some people are clearing out their garage, scaling down/sclaing back, or moving. Some of us do this as a business, or part of a business. There are bargains to be had and treasures to be scored all over the internet on many platforms. I, for one, am grateful for ANOTHER opportunity to reach ANY potential customer that ends in a sale. Low ball offers are part of the deal. I choose not to get too bent out of shape over it. I deal with it daily in my brick and mortar store as well. Some people walk in with a thrift store mentality, others walk in and appreciate the quality and selection I have to offer. ALL attempt to barter. It is what it is.
