Don't know about a code, I just PM'd Joe at QT, and got my free shipping and price matched on my 2 orders yesterday. Took less than 1 day to get a response. If you put in a request in late Friday dont expect a answer until Monday or Tuesday is my guess. I have learned, I need to be patient for good deals sometimes. I know everyone wants their orders to go in immediately and then patiently wait for them to be shipped.
A code would be good if it was a QT exclusive product, is that what you were looking for?
