I needed a deal on Malwarebytes Anti-Malware for 5 PCs. I couldn't find anything great here but eventually found a Newegg deal.

Malwarebytes Anti-Malware Premium - 3 PCs / 1 Year - CD for $29.99 + $2.99 shipping
http://www.newegg.com/Product/Pro...2017-S4A8A

Promo Code EMCEGFK75 takes off $17 making it $15.98 shipped.

I was able to get 2 in 1 order & the coupon applied to both which got me 6 PCs for $28.97 which less than $5 per PC for a year of protection. I assume this along w/ W10's builtin defender is sufficient.

the coupon only worked for the CD & not the direct download version. bummer

PS - this is a newsletter coupon which means you have to agree to subscribe to the email newsletter for it to work but I assume I can just unsubscribe after the fact.

PPS - if you wanted a lifetime sub like me we're SOL because they don't do those any more.
