Hmm, seems like I misread your post. You are referring to me maybe not even having enough time to maintain a spreadsheet, correct? Well, that idea didn't occur to me yet, and I feel I need to apolgize for chosing the negative interpretation of your post.
I was trying to be clear too. Not offensive.
My basic idea was to set up for a container, not a bulk buy deal, as a container is what I myself do need to be happy. I thought it would be considered negative to also have to buy from John at high prices. Now it seems that it is exactly the other way around lol.
However, we can have both options in this deal, people buying from John mainly and others buying somewhere else. Why not? Makes it even easier.
I decided to also maintain a list on this forum and keep it up to date.
Cheers, Thomas
