For EU buyers. Since january 2015 you can save save, or not, if you buy direct from Poland. Compare your VAT figure against 23%. If your VAT is lower than this you will save money ordering from Poland after January 2015. If your VAT is higher you may be upset the price you pay will be highest than expected after January 2015. Most EU countries have VATs lower than Poland.
The reason for this is that from January 2015 the VAT should be charged at the type of the destination country and not the origin country, as occurs today.
