I think trust between buyer and seller is an important thing. But before making sure any order , we need to give a clear direction of our job. I think that helps for all sellers here.
Sometimes we write everything in gig description still people ignore it and make an order. That lastly turns to a devastating situation.
Also sometimes , We seller offer something , that we never able to give.
So we both buyer and seller have to be careful when order or when wish to get product.
The right way I think , seller never put anything what actually they never know , Buyer never ask anything that actually he/she knows never get that price.
