Suggestions welcome on what would help sellers to easier price inventories.
I think Sebi may be sick of me suggesting this but I thought I'd post my idea here so other users can expand on it: Mass editing. The Mass Price Cards (Price All under the Tools option) was added a while ago after some discussion but it is not as extensive as I had hoped. It would be better for the user to just use the trade page to mass edit prices instead of a little pop up window.
In order for mass editing to be effective, card condition and price range (user input) filters need to be added. Allow us to use the current search and filter system to get the group of cards that we want to price. Then allow us to apply an absolute number or percentage of Deckbox's value to that group of cards.
For example, I would be able to filter my cards to show all the NM rares I have - between whichever value range I wish - and mass price them at 90% of Deckbox's value. I would then be able to do that for the LP rares and price them at 80%, MP at 70%, etc. I could even choose to apply this for the modern rares and apply a different percentage to standard rares.
Using the current filtering system - with the addition of the suggested filters - to mass edit cards would allow each user to use the tool to apply price percentages (or absolute number) to whichever filter group they wish. Foils, promos, any rarities, editions, conditions, etc.
