You do have a direct link to the item on your sidebar with no information that a 5:00 purchase is required until you get to the final page of the shopping cart.  If you click on the free fall banner it takes you to the freefall page with your notification but if you click on the image it takes you directly to the product with no notification. 

There are those that would call this bad business and does not reflect well upon Rederosity as a place to purchase 3D content.  I would say that this is just a web editor error but cannot speak for your staffs intent.

Regardless, justify it how you will, if your customers feel they are being misled then you should as a vendor take action to correct the situation.  Either remove the restriction or remove the links to the item that do not clearly state the requirements for purchase.
