Posting affiliate links in the main forum - OK?

Don't know the policy, so I'll point out the behavior, you tell me if it's wrong.

I want to make extra money. I get an Amazon or eBay affiliate ID. I find a great deal. I post it in this forum, but using my affiliate ID in the URL. It's useful to the users, because it's a good find they might not otherwise see.

Now whenever anyone clicks on that link, if they ultimately do wind up buying whatever it is, even if they buy it weeks later, I get a commission as the affiliate that originally referred them to it. I'd imagine you could even do this for vehicles. Find a shortbox, post it here, it sells to someone who clicked on the link, I get a cut of the sale.

Is that against policies? It sounds like that should be in one of the vendor or For Sale subforums, but it happens reasonably frequently, so just asking. I know we can't post "Here, buy my widget!", but can we post "Buy this widget on Amazon and I get cut!" posts?

Thanks,
Dave

PS: To be clear, I've never done either, just asking.
