I hope there will be a lot of new sellers. I love big discounts

Do you like to risk? It seems to me more profitable to buy goods at a slightly higher price, but with a reliable seller than at a lower price but with a seller deal with whom may break.
My experience shows that my strategy is beneficial. It is necessary to look at the seller and evaluate its reliability. Usually they try better than those who already have a good rating.
Well, in this part of the question you are right. Many sellers, getting a good rating and a large stream of orders, relax and approach their duties less carefully.
