Dan, Jim is coming up into this area and can go directly to the shop. I am sure Oliver will acknowledge this instal as one towards your quota and for the same price.
When I initially talked to Oliver I told him of the site and there would be organizers/individuals contacting him and he should give them special treatment.
Dan has really done some great leg-work on this group-buy..
Jim, you might have to send a deposit to Oliver to confirm Dans "Group Buy" price.
Check with Dan/Oliver.
