As a seller we have an obligation in today's market to pick and choose who we sell too. Being first in line doesn't necessarily mean the item will be sold to you. There are many variables to consider. Personally before I sell to anyone I do a complete call sign check on the person. Do I see any red flags? Do I see any complaints from previous sales? Do I see any unnecessary PayPal charge backs? If all checks out than I will proceed with the sale. The above can also be applied to a buyer as well.
