This is what i send when emailing a seller:
Hi, I was wondering if you still have "x animal" available. If so, what is his/her current weight? Does he/she eat rats/mice/other? And what is shipping to "insert your zipcode"? Thanks, Your Name and phone #
If a seller doesn't respond to me at all I assume the snake is sold, if i get a partial answer i respond with something like " Thanks for the information. Could you also "insert unanswered questions" Thanks, Your Name and Phone #.
Also, always use what they say is the best way to contact them. And a phone call can generally get your questions answered.
As a side note I just got a male proven breeder from Lynn at Boas and Balls. I am very happy with the quality of the Pin, and of the business. They currently have 2 male hatchlings for sale.
