If anyone wants to sell off there old erupters in the UK I will buy

As long as they are cheap!
How cheap do you want them?
The
Block Erupter USB is available for
$5 from neXgen Mining now.
Any cheaper and they enter promotional give-away item territory; etch off the existing logo, print/laser your own on

Someone want to explain to me why the unit price jumps to $30 when you put 20 or more in your cart?
