I'm on my 6th baby and all 3 of these items have always been "free." You just have to pay the ridiculous $12.00 shipping (which is pretty much what these products are worth, anyhow.) and risk your CC info with shady companies.
And yes, the PP's that say "you get what you pay for" are correct. As are the PP's who say people have had their CC's scammed after using them for these items.
