Try visiting their website (mcafee.com). I'm sure they have prices on their website. If not, contact them and I'm sure they'll give you a quote. Yugo,.
I am not sure about Mcafee cheapest options but I know that Merchant Safe trust seal is as good as Mcafee and costs much less, only 239 per year! I heard they do even PCI scanning for a much lower price. Take a look at their website for more info (merchant-safe.com or merchantsafepci.com for pci scanning)
MC Afee Secure is good we are using it.. and have no complaints. But the only problem is prices. They are going up every year by year
I am having bad luck with MCafee myself. With the prices going up and up it is becoming harder and harder to justify buying it every year. Would you say it is worth the hassle?
