This saddens me as this is by far the easiest way to sell cards from my collection compared to other sites *cough* TCGplayer *cough* or avenues. I appreciate all the work you put into Deckbox to help keep my collection in order and connect me with other great users for a seamless experience of sharing cards with others who want/use them!
I will keep checking in on the sunsetting process as it moves forward.
Like others mentioned, keeping the price listed for the cards is a godsend for selling/trading and an overall snapshot of my collection and I am glad to hear it will stick around.
