There are two catalogs from the Pacific Northwest you might want to have a look at. Also, one from the Canadian side of the line.
Irish Eyes Garden Seeds might be a little far to pay shipping on their seed potatoes, I don't know, I didn't check their rates. I have some trouble getting myself to buy seed potatoes from a distant specialty outfit because the local garden centers will have them delivered in bulk and sell their potatoes at far lower cost. Problem is, they have only
some of what I want.
If
I want what I want, which is the whole reason for ordering from distant outfits, I should ante up the cost. Besides, Irish Eyes is closer than any other catalog company from my front door

. Irish Eyes also sells packets of seed for all sorts of crops so sneaking a couple pounds of potatoes into an order may not make you feel embarrassingly self-indulgent.
Things are changing with the other two outfits - first the one where I have seen some of those changes over several years. My involvement Osbourne Seed doesn't go back as far as my orders from Johnny's, on the East Coast. (When are these outfits gonna give some customer appreciation credits for people who have been with them for the last 40 years? How about just a senior discount

?)
Anyway, my involvement doesn't go back as far but
Osborne has entered the top tier with a beautiful 2016 hardcopy catalog. Finally, their price list isn't separate. Be sure to look at the price list there in the the glossy format. Everything they offer isn't accompanied by a big, colorful description and picture. Packets are large usually but they have really trended towards broadening their appeal and even those people with small gardens should find some interesting varieties.
I've been watching
West Coast Seeds just over the Washington/British Columbia border make big changes with their new owners. Yes, they ship "across Canada and throughout the United States!" I have yet to order from either the old or new owners but if organic seed is what you are looking for, check out this outfit, just a short early morning ferry trip for
@aftermidnight
