I haven't had any luck yet. I only sent out 3 emails so far. I gotta sit down and send some more out. Advanced was the most decent I've heard back from. They sent me a bunch of PDF files on their products and a 32 page file on PH that was pretty informative.
I talked to Miranda a rep at Beeline and she is going to send me out some sample. Time Blanton the operations manager at Cutting Edge sent me a nice message about how they used to sned out samples but now they only send them to retailers. Collective Supply wants me to set up a business account with me before they'll send me samples. Supernatural told me to talk to my local retailer. Rootbastic just said they would get back to me.
Botanicare will send you 4 samples but you have to pay $16 for shipping. Still saves a lot of money. I had one sent to me and the other to my gf's moms house. Paid $32 for over $100 worth of product.
AN is sending me their line of products!!! Here's the response I got: Hi ********, Thank you for your interest in Advanced Nutrients! Please let us know what your favorite local authorized retailer is Thank you, Talissa Andres Advanced Angel
