exactly...and how often do you use the warranty you purchasedTake a lesson from Dave Ramsey here guys. It's already got a warranty from the manufacturer and if it doesn't, I'm not buying it!
ok as a former best buy employee and knowing the scheme. here is my advice.
1) never buy it on anything except laptop computers.
2) only buy it on laptops if you plan on keeping it for several years.
3) after purchasing the plan for your laptop wait 6 months then call and get a new battery for your laptop. You will now have two batteries for your laptop. This excludes apple products which they didn't sell when I worked there.
Read carefully as your mileage may very and rules may have changed in the last year or two.
