Buyers should beware of sellers who are abusive and defraud buyers. They sell scopes at low cost but don't deliver or they deliver defective optics (factory rejects, or broken used scopes). Returning scopes to them often ends with the seller receiving a negative feedback, no scope, loss of s/h, loss of return shipping. The bad seller then resells the item next month. A prime example of this can be found here
