I recently reordered some TF-4 (I was also confused by the description of TF-5 and decided to stick with the older product, which still seems to work fine for me). I almost didn't because of the high shipping charge. Then I went to the Digital Truth site, ordered the same products, and the shipping was $10 less. What really makes this nonsensical is that the order was drop-shipped by Formulary. So it was coming from the same place either way, it just cost less to order it from someone else.
