I can only assume you're being purposely obtuse because no one can possibly be so stupid as to not understand what I'm saying. Not replying to my email because they weren't interested in my price is rude, plain and simple. That's my issue with them. If they were only willing to pay the amount in their first email, they should have said that, or they should reply to say no thanks. It takes all of 10 seconds to do and goes a long way towards giving a positive experience to a potential customer.
