Rick has the best suggestion if you want to save some money. Pick it up at the range if the range master will let you. Some of the indoor ranges around me don't let you pick up brass unless it has landed by your feet or on your bench, and only in your stall. All of my outdoor ranges actually encourage you to pick up all the brass you can as long as you don't interfere with someone else's shooting and of course only pick up brass when the line is clear and shut off for safety reasons. That being said, you'll most likely have a better shot of picking up quantity at an outdoor range and quality at an indoor since its not subject to the weather elements.
