Are cheaper wines no good?*

That's what I thought too, but I have been since informed that:

You are allowed to bring back 2 bottles DUTY FREE.

You can bring back as much as is reasonable (Not a truckful but a few cases should be ok). Just declare them and they can put taxes on them. But the taxes are so low, they generally don't want to spend the time on the paperwork. Taxes are higher for spirits though.

When you cross the boarder, just be upfront and tell them what you have. they will most likely just waive you through. Of course, you may want to confirm this at the boarder before you cross too but this is what I've read on other posts.
