Query: $100+ ??

I've used a G5 mouse for a year before the right button gave out after a drop off my desk. Coming to Amazon.com to get a new one, I was astounded to see this mouse at first $176, now it's lowered to $140!? I bought this very same mouse at Best Buy for about $50 brand new in the box. How in the hell you can justify a markup of this amount is insane. DO NOT buy this mouse for anything over $70 tops, simply a stupid price tag.
