If you don't provide a vouch copy, no one is going to buy from you.
Wrong. I haven't provided vouch copies for two of my other threads and yet, I have already made some sales.
Not giving a way vouch will only make a bit harder to make a sell but does not necessarily mean there will not be any.
Vouch copies: No How do you expect the intersted people to know your claim is right or false ?
I don't expect from anyone to believe or not. If a person is really interested and there are no vouch copies offered by seller, he/she will put a little more effort into looking of the sellers account, checking profile, checking trusted ratio, checking other seller threads and have there been vouch copies offered, were them good or bad. There are other, indirect ways for making a decision about seller and his reliability if he is not offering vouch copies. Also, there are and pm's.... a lot of tools to decide are you going to trust and buy digital goods from anyone or not.
Price: Not less than 25$. Take it or leave it. customers are king, you dont give them orders.
Yes they are. Now go to buy Mercedes, BMW or Tesla car for 1000$ as you are the king.
It's really interesting to see that most of the replies goes toward the criticism of the threads and their content while most of the private messages goes toward the details about the offered digital goods or selling details. Anyway, thanks for the replies and shown interest.
