Hi need help in choosing the VAT refund option for a Europe trip. Mostly my shopping will be done in Spain, i have shortlisted to Utu or Global Blue as the preferred option for refund. Utu is a bit new, they are advertising 80-85% refund but not got many reviews online about their authenticity. Global Blue has good review but for sure they only give back 50-55% refund and charge extra for currency conversion etc.
