Here the price is much cheaper. But some good advice:
* The harder the better
* the darker, the better (darkbrown)
* when you want to crumble/grind it: heat it a bit, be sure the hash don't light up or turn black (burnt hash). Just heat a bit so it will get pliable. Then you can crumble it nicely.
I've never tried bubble hash, so I can't say a thing about that

But I love to smoke hash together with some greens :stoned:
