That link Patrick applies for upgrading from Snow Leopard only.
Then finally Click Here:Mac OS X Yosemite 10.10.3 Free Download - All Mac World go here and click on the grey box where it says download
It will open another page and if it doesn't download it automatically click where it says

I need 10.11 to update my apps. My APP store does not have a 10.11 upgrade listed.
I am sure there are plenty who have this same problem.
That link Patrick applies for upgrading from Snow Leopard only. Maybe glory has Snow Leopard DVD, could do a clean erase and install and then follow your link?
