There is a list of reputable camera shops. Stick to them of you want to get good deals - but never forget your homework. Shops are not charity.
Check the small prints of promotions, I remember there is a buy back program by Canon. IT shows have this name because .. it's about IT, not cameras. Apart from some rare occasions they just sell for standard prices and throw in freebies of little or no use. No point getting "pampered" with so-called freebies if you need to buy that stuff later again to have it properly (e.g. tripods, filters, cleaning kits).
