I woke up today to find that I made $1.44 this month from Amazon! 
One of the purchases was a product I linked to from an eHow article! The other came from TNB #3 site, which is starting to rank well (which means I should probably start paying more attention to it!)
I haven’t been as busy these last few days since I’ve been so tired at night. I’ve been doing keyword research for my next sniper site but haven’t been having a lot of luck yet finding just the right thing. I did do a post for TNB #1 site last night. I noticed that it slipped from #1 to #5 in the SERP and I could tell from the decrease in traffic. So I hope a new post and maybe building some more links will push it back up there (or maybe it’s just the Google Dance at work?).
My first sniper site is not ranking at all with Google and Yahoo and is #3 with MSN. But no visitors yet. I may need to do extra promotion with it. Or maybe it’s in the sandbox for awhile 
That’s great that you are getting amazon sales! I have yet to make one. lol
I also have a site that has been sandboxed. I read some more information on sandboxing today and it could take 3-6 months to come out of it. You should still add more content to it and back link it. It will slowly come back. It’s not a total waste unless it is deindexed.
