If you purchase Cisco Access Points model 3500 in ECO packs you will receive a WCS PLUS+ 100 access point license for FREE!
I understand when ordering the ECO pack, there is a special order number so you will need to ask your reseller.
The PAK license for your 100 access point PLUS+ is actually in EACH ECO pack. So if you have someone install your access points, make sure you pull the PAK from each box.
If you are like me and did not know the PAK was in each box. Talk to your Cisco Sales Rep. He can have all your PAKs converted to a single PAK, if you ask him/her nicely … LOL

Q. Are 10-packs available?
A. Yes, the Cisco Aironet 3500 is delivered in 10-access point eco-packs that reduce packaging waste by more than 50% and can reduce shipping and installation costs. Additionally, the eco-pack includes a WCS PLUS Upgrade license for 100 access points at no cost.
Enjoy !
UPDATE -- Cisco ended this promo July 2011... LOL day late dollar short !
