I recently bought a pair of Pearl Izumi cycling shorts for 50% off at a LL Bean outlet in Rehoboth Beach, DE. Also picked up a reflective cycling vest for $4.
I was the Japanese dollar store Daiso (well most things are $2) in Seattle and bought a waterproof nylon cover for my bike basket. They also had metal baskets for sale (they were more but less than $10), reflective bands, puncture repair kits, drink holders, waterproof hand protectors that fit on the handlebars and even an umbrella holder to attach to your bike!
