Is there a way I can exclude certain sellers when using the Shopping assistant? There is a particular seller, Commander_Bacon with who I had an awful experience with and do not wish to deal with them. However when using the shopping assistant it lists this particular seller in every available package as they have a large array of cards with low prices (the prices are not accurate they attempt to charge you more than the card is listed for) and its making it essentially impossible to use the shopping assistant. I appreciate any and all helpful replies :)

As a premium user, you can block another user, which eliminates them from most areas, including Shopping Assistant cart suggestions.

It has been argued (validly, in my opinion) that something as basic and necessary as user blocking should not be behind a pay wall. But as it currently stands, what you ask for IS possible in an upgraded account.
