Patrolbase boneyard has got an extra 50% off now which makes it mostly sensibly priced finally! (excluding novritsch stuff which is still original prices).
A lot of the good stuff has gone unfortunately but there's still a few good bits in there. There's also lots of aeps for £20ish, kwc/cybergun deagles, specna snipers.
I miss the days when they had a well priced boneyard. Nowadays it's more like a £200 RIF snapped in half and missing a magazine with £30 off.
