Now a days there are buyers who will find your gig and ask your offer for a huge number of order. What ever the big price you offer they will not bargain and they will say okay with the price, but they will not accept your offer, instead they will say “okay you complete and show me one number and if i am satisfied will accept your offer”.
For example one of my gig is offering 3D Mockup of product packages. They will ask offer for 20 and will ask to finish only one and show.
Actually what they want is only this one. Once they got it done they will simply say “Sorry this is not i am looking for” and after that they will not reply to you.
If any sellers who face this kind of situation ask them to make the order only for 1st sample and do not send anything free.
