I'm just curious, anybody know if you can actually completely benefit from trading?

What I mean is if you do your hard work, obtain 40% better prices (Through the Haggling Perk)

and on top of that, add in an extra 29% better prices (Through enchanting)

Anybody know the math on that? Are you still losing money if you're buying and selling the same items, or does it even out to about the same?

If anybody knows the math on this or a topic where I can find it, let me know please.

In addition to my last sentence, all I care about is if you're still behind, even, or ahead when it comes to buying/selling after you're at 69% better prices.
