I heard about this a few weeks ago...Well this effects different people differently. My LHBS, as an example, is going to have its selections of LME slashed. While I do not use TONS of LME it sucks for them because they sold a lot of the Cooper's kits to people just starting out.
The way I understand this is that Mr.Beer is like a mini-franchise, This is why my LHBS does not carry them. The profit margin is low and they dictate the prices. Also it does not go through the standard distributor for supplies but a specialized one.
I have also heard that Munton's is going under or is having some other sort of issues.
This means I will ONLY have Breiss unhopped LME and the LHBS is going to have to find something else to fill a massive section of shelf space. So from a "support your local LHBS" stand point, this is a BAD thing.
Please remember I am trying my best to repeat what a very fast convo was about so I use this info as loose information and not hard facts.
