Alein,
I believe you and many others are missing the key word here MSRP, or better known as Manufactures Suggested Retail Price. EVERY MSRP I've seen has always been much more then what the item really sells for retail. The MSRP is just that...a Suggested price, nothing more nothing less.
Traxxas is giving this offer of 50% off based of the MSRP, not retail. There's a big difference in the two, there's nothing over inflated about it.
However after viewing Traxxas's website I did notice this: "50% off of the current retail price of the new engine." This I find pretty mis-leading, as I've already pointed out the difference between MSRP and Retail, and by stating 50% off of the current retail price is in fact the Tower, or other hobby shop prices...MSRP is no longer.
Then again thats just my 2cents.
