If you’re planning on doing one every day then I think a ‘
Special Offers…’ topic would stand out more and get a chance of more attention. 
I’ve seen quite a lot of people with US locations in their profile, so you may have more of an audience than you think. 
If you want a hand I’m happy to help.
If it’s the occasional one then I think slipping it here in the 
one shouldn’t be too confusing with a and the $price.
I’ve also done a quick DOTD template if anyone needs one.
