It would likely belong in Off-Topic, and I'm sure it's allowed. Every so often if there's a good Amazon online sale, someone would post it. A couple years ago, I went to the trouble of posting a huge Amazon sale on 20th Century Fox TV titles, making sure each individual link for a title had the "support UD" code in it. Of course, since then the individual code thing doesn't work anymore and it's usually just through the affiliate link.
Mostly, though, any special promotions end up as a post in Pals's "What DVD are you gonna buy on (insert week, any week)???" thread. But still, I'm sure a standalone thread devoted to different offers and sales would work in Off-Topic.

When I said "here" I meant this site. It would be in the "Off Topic" for sure. If it was Amazon, I wouldn't have even asked. But it's a main competitor of Amazon so that's why I wanted to ask.
Feel free to post it. We have lots of affiliateships (none as fruitful as Amazon, but they exist) so it might even be a site that linking to can support UD. If not, well, still, you gotta share the wealth, man!
