It is considered impolite to plug your own stuff without disclosing your relation to it within the same post.

I was just looking at your pricing page and the greyed-out-but-still-ticked items in the comparison lists are very confusing. Being greyed out makes it look like their not included, but there's still a tick, so maybe they're still included but less capable? Or available as an add-on? I can't tell what, exactly, you're trying to convey to potential customers.
