why would it cost you $1 to list a $1 item?
If you put up 10 of the same item for $1 it would cost you 50c
every one you sell you pay 5c fees, sell 10 and then it costs you $1 all up, for $10 in sales for cards worth 10c each.
then he charges $1 post for 1 card and 20c for every other, he sends a 60c stamp, so you buy 5 cards for $5, you pay $2 post, he makes $1.40 profit on post which off sets paypal payments, the $5 for the cards worth less than $1.
most sports common sets contain about 180 cards, so $1 per card from a common set you can't sell for $12 on ebay, so over time, your affectively selling common sets for $180, pretty good mark up if you ask me.
high level power sellers need to maintain i think 2000 listings to get a special rate, maybe even better with 10,000+ listings.
I have always said, it's a lot easier to sell 200 x $1 junk items then it is to sell 1 x $200 item.
but yeah, it's probably not even the money, think it's more to cheese everyone else off, he doesn't get what he wants anymore, 50 cases a series is well and truely over since it's all been controlled by the one distributor, so this is his way to earn a quid and cheese off everyone else by flooding the categories.
