It all begins with finding the coupons. Getting a Bitdefender coupon that delivers the best bang for your buck is not difficult if you know where to look. The first place to go for such coupons would be coupon aggregator websites. A good way of keeping track of the latest coupons being posted by such websites is to select a few of them (since there are so many) that provide coupons for the types of products you purchase most often (in this case, for antivirus software and computer programs) and then bookmark them on your browser so that you can monitor them more easily. That way, you can simply check them every week or so to see if new coupons have been posted that may be of interest to you.
This does not mean you should not check other places, of course. Look for coupons and deals on the sites of official vendors of the program you want to buy and sign up for newsletters as well as social networking feeds for the companies or brands concerned. This keeps you tapped into them and aware of any discounts that may be coming or already in force.
You should also check coupons expiration dates before discarding some: the ones you may be keeping just might turn out to be expired already. Only after you have thoroughly compared and inspected all your Bitdefender coupon options should you make a purchase, which should truly be the best buy you can make under the circumstances surrounding you.
