Wise Food Storage

They advertise that you can go on their website to order a free sample before buying. I ordered a free sample and everything went great. I then get a message from the company asking me to pay 3.95 for shipping. I have the order confirmation which said free. I wrote them back saying that is a scam and to keep their freeze dried food.

Email from company:
We received your request for a sample, and wanted to make sure we get that sent out. We just need to collect the $3.95 shipping charge, and verify your shipping address. Please call me at *******369 to and I can process the shipping charge and get the sample sent out right away. Also, the address we have is as follows, please verify that this is correct.
