This is off topic, but pricing for these is confusing me.

I thought I bought the Mag model today. The shop "discounted" from $199 retail. However, on the cycleops.com site they list a retail price of only like $159 or 179 for that model. Then mine has a Trek label on it, so don't know if Trek tries to jack the price up, if the shop did, or if I got another model?
