They are correct, option 3. The 110% is of the difference. Hardly makes it worth messing with the headache, as most retailers throw an absolute hissy fit and try to worm out of their own policy. Best Buy requires you to actually purchase the item at their price and sometimes even leave the store and come back, before they will even consider it. Circuit City and a few of the office stores have actually halted this policy.
The only one I ever shopped at that made this worth your time and followed their own policy was Office Depot. They used to do 155% of the difference, but have since quit. Used to get freebies from them every now and then. I would do as much shopping there as I could to reward them for following their policy with little to no hassle.
