Originally these sample packs have a $5 shipping charge. However as part of their one-off promotion, you can get free shipping by doing the following:
Simply send an email to [email protected] asking if you could please get a code for free shipping to try their sample pack. You will shortly get a reply from a customer service rep with a unique voucher code. Once you have your code, just go here and add the sample pack to your cart. Next, enter the code during checkout and your sample pack and shipping should be free.
