Bought 145€ worth of codes, the seller even sent me 5€ first to test if it works in my country and answered bunch of my questions beforehand, seems friendly and reasonable.
Will update when I order something during Christmas, We used MM but since I'm not ordering til Christmas it doesnt seem fair for the seller to wait til then as I've changed my mind about when I will be ordering something after we have already agreed the framework of the deal.
just a small update: went and ordered my stuff, received it with no issues.
