DD, TCG does convert for me, but there's periods where I'll see alot of clickthroughs...but no conversions. Last month was one of those months. You're right though about the uniques/sales.
I know it's the holidays and maybe there's a hundred more reasons. But oh well, they do convert and I'll still be pushing them regardless. Even though the sales suck from time to time.
UW: LOL you're a riot
