I purchased my copy of Grow Bulbs from Silverhill Seeds before the PBS group offer. The cost of postage was almost as much as the cost of the book. I believe at the time Arnold organized this group order he estimated the cost to ship it out of the country and concluded that it would cost less for people who did not live in the United States to buy it elsewhere if they wanted it. In other words there would be no benefit to overseas members if the extra postage cost was added and it would be a lot of extra work for Arnold. Silverhill Seeds still offers this book. The Pacific Bulb Society only charges an extra $5 for membership for people who do not live in the United States. This does not cover the extra charge to mail the Bulb Garden to members who do not live in the United States. When I was on the Board there was no discussion about raising the rates for those members because international members were valued. Mary Sue
