Are they good deals ? - Well that depends, firstly is it what you want if that's the package you want and cheaper than you can buy elsewhere then Yes.
But if it's not the package you want, then unless it's hugely cheaper than market price, 20-25% off, I don't see how it's a good deal
Also if you don't need/want the extra bits I can't see the point, just buy the rifle.
Deals like this are to shift the "big profit item" the rifle , the scope, bag & pellets are probably at break even value so that he can make the profit by selling the rifle effectively at it's RRP.
