GUITAR CASE PARTS

Haggling at Guitar Center?
Okay, so I’m going to purchase a Yamaha FG730 acoustic guitar and can get it with picks, strings, strap, humidifier, tuner, and a case for $338.93 online (it’s part of the store’s spring sale). I think that’s a pretty good price (but of course I’m a total newb at this so what do I know?).
Anyway, so what are the chances that I can get this same deal (or even a better one) at Guitar Center if I bring in my printed cart from the other store’s website? I want to know because I really would feel more comfortable buying from an actual store than online, but I want to get the same deal as I would get had I bought online. And apparently, GC doesn’t haggle anymore. So, like I said, if I walk in with my printed cart and cash and say “I want this guitar (and the extras) for this price”, what are the chances that they’ll give it to me?
