I am a small business owner, and there are some smaller, local companies I do business with and have had some very good experiences in dealing with them.
Llewellyn is one of those businesses. They have been in business for many years and deal in a small nitch publishing.
I have had experience with them on two levels. As a book distributor, their prices to the trade are very good, the same actually as some of the larger houses. They have a set % of the face value that is for book dealers, and they vary this depending on the volume you purchase and the sales you can get occasionally. Shipping is also discounted based on volume.
The forms to fill out are simple enough, and all my orders have been promptly filled and shipped.
I also deal with them as a publisher. I have had some of my articles published in their annuals, and the staff is courteous, the editors are pretty good and the finished product is very professional. Payment is always on time.
A good publishing house to do business with if you are into the smaller nitch that they specialize in.
