Mselica,
Welcome! I think you'll love SBD! Please do keep in mind that with any new WOE, but especially this one, you'll do much better if you read the book and stockpile the foods you need before you start. Wait for that book to come...I think you'll be much more successful!
As to the syrups, you can order them online, but to avoid shipping costs, and perhaps pay less, check places like TJ Maxx or Ross Dress for Less in the home areas. In addition, you can usually order the syrups from small coffee shops (not chains) in your town. I did this successfully and so did several other SBD chickies.
Good luck and welcome to the beach!
