Yes for me it is a problem. Now buyers are more confused about what to buy. With fixed pricing buyers used to come to the market, search for their required keywords, gets the results, walk through them and purchase the item they find the best suited for their project. So in all whatever they purchase there was a surety that they have purchased it for the right price and nothing can be purchased cheaper than that. But now they are confused with the different prices for the same kind of item, they are sorting the search results with price high to low, low to high and getting amazed by seeing the difference. In all this is making them postpone their decision, losing faith in the market, searching again and again to get the cheapest item or the most expensive item. This is the reason why we all have good traffic these days but that is not converting as it used to be.
