If you do these make sure you read up on the user comments on SD. The companies are extremely picky. I've done about 15 of these in the last year and some of them needed followup and sending them copies/scans I made of my submission form, UPC code, envelope, etc. I believe kaspersky is one per product per year, but some only allow one rebate from their company per year. Out of all those rebates i've only had one not return, thankfully only for $5. After my experience these rebates are only worth it if the product is something you truly want AND if you are very organized.. Tried to sell the products on amazon with open box at heavy discount but either have 0 interest or the companies contact amazon to take my listing down.
IMO the totaldefense combo rebates usually makes some valuable expensive products FAR. I would only go for a product that is valued over $50. it required badgering their CSR months later but it is of pretty decent value and you can reliably get the money if you follow the rules to the T
If you use a modern version of Windows (7 or 8) and you're not browsing shady sites like triple x, war3z, or MMSecrets i no longer find the need for 3rd party antivirus programs. Windows built-in AV software is very good and anything else will just slow down your computer.
