It's $80-90 right? That's what I just looked up. They claim around 100 sales or borrows which is pretty good. But, personally, I prefer really high marks if I'm gonna experiment with a promo site close to $100. I haven't tried them.
I was considering gambling on a much cheaper promo site, crave romance, if anybody has any luck with them. They're like $7.
I'm experimenting with mid priced promos that have good recs through the internet. I'm booked for an upcoming promo with excite steam, hidden gems, pretty-hot books, and full hearts romance. I can only vouch for hidden gems, as I tried them before. The other three seem to be well received.
Of course, Red Roses Romance comes highly recommended if you have 10 reviews. I haven't used them, either, but I always have good luck with their sister promo site, Book Barbarian.
