Add the sample to your cart, then During the checkout procedure select the “I am only ordering samples” payment type to complete the transaction. No matter what the $ amount is, you will not be charged when you use this payment type. If you try to use the “Credit Card” or “PayPal” option, it will result in a charge for you.
