Very interesting Jurek - as always you bear listening to!
reminds me of a guy I know who had a business fabricating wire baskets, shelving and such for closets in the home construction business.
He couldn't believe his good luck when the Home Depot came to him and offered to buy his entire annual production, at a good price, on an on-going basis.
A few years down the line, they let him that he would have to cut his prices, or they would go to another source. He complied, but was hard pressed to be able to do this. Actually, he had little choice, since his other former clients had long since found other suppliers.
A few yers further on, HD requested another cut in prices, which he couldn't meet. They went elsewhere, and he went out of business.
