There are currently 2 separate promotions available. One promo is a $500 price reduction on the Terra Servers (either model), and in addition, if you purchase one of these Terra Servers you have the option of adding a Strato-C at a $2,000 discount off of msrp (from $4,995 discounted to $2,995). You do NOT need to trade in components, these are a straight discounted purchase.
The other promo is aimed at Premiere owners that DO NOT currently own Strato/Terra (the goal being to have Premiere only owners add a Strato or Terra to their systems).
If you own a 1U, 1U+, 3U or 5U, you can add a Terra Server at the stated discount, and get both a store credit ($1200 - $1600), and a free download service from K.
If you own an M-class Player (M300, M500, or M700) you can add a Strato player and get store credit ($300 (C), $600 (6TB), $900 (12TB) and a free Co-Star Switch Kit. Currently scheduled to run through March 31st.
EDIT: 08/13/21: The above posted Promotions are no longer available. Contact your Dealer for information on current Promotions.
