I'd gladly help you out, if I could find these sales myself! I live in San Francisco, and I always seem to miss all the great sales in the area. Once I figure it out, the shelves have been picked clean.
I've only been luck once, when I found some train sets I purchased as a present for my father.
You should also check out the web. For example, I've found great deals at Amazon.com and eToys.com. Nothing right now that I've noticed, but you should check every once in a while!
