I have dealt with 27 of those vendors. Nothing on facebook, of course. Some vendors are listed 2 or 3 times, so I just counted as listed.
Oddly, after I started doing the newsletter, many of my prior efforts fit. The vendor list, for example, came from a prior work. It is much easier to update in the newsletter, than online, and keeping it current is still difficult.
The newsletter vendor list is vendors who consistently provide high-quality products and good customer service.
