Hey Crystal!
I'm new here too and can understand why you haven't put some "chatty" threads up, because to do that intentionally then post your site would definitely be spam as ecchi mentioned. Well, that's the way I would see it.
I checked your site out, I think its look great especially if you compare it to some of your competitors. How did it perform during split testing? That's what matters more than the 'look', however I think its 'look's great!
I might be wrong but I thought that flat designs were really responsive and up and coming, so...
I agree with the point about the prices however when it comes to traffic and advertising its not always just about price, ROI is more important than the actual bid price so I guess it won't matter to people if they see results.
Anyways, great work!
