Super plugin!

I am using both the free plugin & the attributes addon, and both are working great.
I’m seen some people have trouble, but you need to be careful with the csv file, making sure it is saved right (comma seperated, UTF) and use the correct field names and it will work for you.

The only bug is that the shipping class (for sales tax) doesn’t seem to get activated after the import.. so you have to go to the product page and click update, and that makes the tax class work. It would be niced to be fixed but not a big deal as it only takes a second to press update on the product page after importing.
