I bought a Rebel XT from Best Buy along w/ the extended service plan which expires in about a year. I'm not sure if I'm allowed to discuss this here , so mods delete this if so. I'd like to use the service plan to get them to replace my camera with a Rebel XTi. I know in Florida, the lemon law (or something - maybe it's just best buys policy) that after 3 issues or something, they have to replace it? Any advice on what to say or do?
