Well.. every time that i insert a new product i have problems in setting Final Price it's very sad to do that but i dont have solution..
So..
We insert all product fields (name, sku, etc.. ) the TAX / VAT (in my country it´s 23%) and then hit the field "Final Price" for 400€
Then HIT "SAVE"...
The page refresh and you'll see that the "Final price" is NOT Correct because the final price that you insert "400€" -> go to "Cost Price" and "Base Price" 400€ ..
and every time that you insert a new product you'll get different final price... now do that for 1000 products or more products!
It's very boring! :( :( :( :( :( :( :( :( :( :( :(
