Do not embed links to deals on DVD sets or websites you want folks to visit in every single post you make. You can post the links in your sig only. If you embed links, they will (and have been) be deleted, you will get a warning and if you continue to post those links, you will be banned without warning.
There is no reason to continue posting such links in every single post.
I started a thread for folks to share the deals they find on the DVD sets here.ETA:
You can post links in your FIRST post in a thread, there after it is not necessary to continue to post the same exact link in every single post you make.
