Every blog post order does come with an absolutely 100% unique post on each site in the network. For instance, you are asking about the Sports niche. That would work perfectly on the Fitness network, which is angled towards exercise through outdoor activities like sports and running or activities at the gym. So for the $85, you would receive one unique post on each of the five sites. That's five total unique posts, one per domain.
I hope this helps clear things upThanks for asking. Let me know if I can help out any further!
All this time I thought it was 1 post for $85. But $85 for 5 niche relevant aged PR incontent links? That's unreal. Doesn't get much better than that. Just an FYI as you might want to make that more clear in your sales copy.
