This is such a good idea: Edward Champion has compiled a list of quality independent bookstores near every single one of the 200 soon-to-be-closed Borders stores. Here's his entry for the two Borders that are closing in Washington:

Borders Bookstore #234
4601 Point Fosdick Dr. NW, Gig Habor, WA 98355
A Novel Bookstore, 305 1st St., S. #1, Yelm, WA 98597 (24.6 miles)
A Good Book Cafe, 1014 Main Street, Sumner, WA 98390 (31.0 miles)

Borders Bookstore #619
3000 184th Street SW, Suite 910, Lynnwood, WA 98037
University Book Store, 15311 Main Street, Mill Creek, WA 98012 (4.0 miles)
Edmonds Bookshop, 111 5th Avenue South, Edmonds, WA 98020 (4.1 miles)

You should forward this list to people you know who have been affected by the Borders closure announcements.
