Molbaks in W'ville has several 2 & 5 gallon H. Quincefolia for 30% off up to a few months ago. I'm not sure if they carried 'Pee Wee', but you could check there.
Otherwise, Classic Nursery on Avondale Rd in Redmond has Monrovia grown 5 gallon Pee Wees for $40. They need spraying for leaf spot but then new leaves look good.
Continuing 1 mile north on Avondale is the reopened Gardens at Cottage Creek Nursery. They also had H. Quincecolia 2 Gallons for about $20, but I'm not sure if it was 'Snowqueen' or 'Pee Wee'.
