Ok buying this camera for my wife don't know much about cameras so maybe u guys can help... The body alone is 450 the body w 18-55mm vr lens is 550 ( leaning towards this) costco has the bundle w two lenses 18-55 vr and 50-300 vr for 800 which is a good deal too... My question is should I get the bundle from Costco or get the bundle for 550 and save up for the 70-300 mm vr lens which I've heard is better than the 50-300mm just more expensive by the way I have no idea what the numbers mean
