I have a brochure that I made up to give to people who request wholesale info. It has my wholesale pricing with pictures of all the different types of candles I offer, a list of all available scents, terms & conditions, contact information, and since I sell palm wax candles I also include an explanation of what palm wax is. As far as a letter is concerned I would probably just explain to them what is in your brochure, and why your candles would be their best choice. Just say anything that you would say to them if you were able to meet with them in person. :smiley2:
