tu jest właśnie problem bo:
"The promotion runs in the following 15 countries: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Luxembourg, The Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. For the cashback to apply, the products on the listed in Section 2 must be purchased in either of those 15 countries"
Więc cały trik polega na tym żeby zdobyć rachunek właśnie z któregoś kraju z listy bo inaczej ze zwrotu nici.
