I own a sd500 and the accessory's for it

during a move i lost all the accessories for this camers. what will a new accessory package cost?

Well, that largely depends on what accessories you had. You mention "package." Did you buy this camera as part of package deal? If so, packages are often put together by the seller to entice customers with a deal for purchasing the package and saving money over buying everything piecemeal. It is often not an official package of the manufacturer, can change it's contents from seller to seller, and often will include accessories from third party manufacturers.

I mean, I can point you to Canon's website for the list of accessories they have available if that helps ... but without knowing what was in your package, I'm just making wild guesses as to prices for any particular package or it's contents.
