Raintree Nursery up in Wa is offering them much lower in cost, mail order or at their garden center.
A quick call to the Horticulture Dept at Wash State Univ. or Oregon State might be able to hook you up with a local source. I find most colleges can recommend a list providers of various local goods and services and are happy to do so without steering towards a particular company.
The Hoods sound yummy too. I was looking into them when dd went on vacation but she wasn't interested
