Yesterday, I found the APC 10Wh USB Power Pack for $20 (normally $50) at Staples. I didn't find it on their website, but the local store had it where you get wireless accessories (basically, a big shrine to Palm stuff; you'd love it ;-)).
Today, I got a Logitech Driving Force GT wheel at Best Buy for $99 (normally $150). It wasn't marked at that price, but it came up at the register with the correct name but much improved price. I found it on the website after I bought it.
