Your order has been received. Please allow 4-8 weeks for delivery.
Their terms of service say:
"...CONCERNING THE FREE SAMPLE
Upon signing up for the free sample, we make no guarantee that you will receive a sample. We will do our best to fulfill all orders as quickly as possible until our supply runs out, but please understand we have a limited supply and a lot of demand, so we are often unable to make it publicly known that we have run out of samples before applicants have submitted their request for a sample. Legally, you are in no way entitled to a product from Al's Pistachios as a result of filling out our form."
The good news, their terms of service also specify they will not sell your contact information.
