Professional buyers picking everything clean
Till a few months ago i had a system like offering a few staples below market price and everything else at or slightly over trend prices. Players building new decks or collections bought the "good deal" and filled up their carts from my inventory. Of course sometimes they scooped up only the bait, but overal this helped me selling at better margins and get rid of otherwise slower moving cards. Until recently.
Now every time i throw out baits they are getting bought up within 24h by professional sellers. It does not matter that it is five fairly specific cards used in five different decks, i guess the only thing that matters to them is resale value cause they do not buy matching cards with them. Private buyers who usuallly have done it in the past now cant even see the deals.
Do you see a trend in TCG resellers getting more aggressive lately with buying, or its just that im having some bad luck? Is there a way to exclude professional sellers from the pool of buyers who i want to deal with? I cant block them individually, there are too many of them and most of them have multiple accounts.
