I've got Ryan Hall Back Attacks - 3 DVD set. Have a look on youtube or on budovideos. It is excellent - he's the best instructor I've ever seen. New it cost about $125 USD. I'm selling for 29.

Chris Brennan No Gi Guard Passes. Only good if you do no gi - but if you do he covers everything from butterfly to rubber guard and throws in a few extra submissions. New it cost $39.99 USD. I'm selling for 10.

Andreh Anderson closed guard sweeps. I'd never heard of him before, but this was actually really good (all gi). Selling for 5

All perfect condition. Buy all 3 for 40 (which I think is around 70% off the price they would cost you new!)
And Postage is included!
