Just ordered a Aimpoint M4s off of SWFA"s Ebay store. I got the 25% discount thru Microsofts Live search and then 10% more with a Ebay coupon code. Total price for a $702.00 optic was $454.96. Will go great on my new Noveske.
You need a Hotmail account. Go to Live Search. Log on to you account (Hotmail address & Password) Then do a search for something ( I used Wii) At the top part of the page you will see Wii Ebay.com and next to it will be Live Search cash back. Click on that then search on Ebay for what you want. SWFA has an Ebay store. You have to use Buy it Now and pay for it with paypal. You will get a cash back payment in 60 days.
