I just found this site: latienda.com, an online store that sells delicious Spanish food and other things in the US. This is just an extract from their site, so you can see the kind of food you can find there:
Food and family are the essence of Spain. Since 1996 we have been traveling the countryside of Spain seeking out remarkable foods, especially those made by small family producers. It is our mission to offer the very best food from Spain, thereby helping preserve traditional Spanish culture and cuisine. We hope you will enjoy this diverse and delicious collection of Spanish food.
