Larry, I don't know what happened there. I thought I did use your link. I didn't get the discount and later got an e-mail with a discount code that didn't work. I contacted customer support and jumped through some hoops and kept getting automated emails stating that the case had been resolved but still no discount. Just when I was ready to give up I got an email that stated there was a $10 credit in my account so I placed the order. Right after that I got another request for more screen shots, go figure. It was somewhat of a debacle but I ended up ordering the cans. Sorry you didn't get credit, I really appreciate your dedication to the cause here.
