Cheapest Xbox Live 48 Hour Codes I've seen so far!

I've been buying from G2a normally but i've recently found this on ebay:

Never bought from ebay before, what do you guys think?

It´s all about the seller, always buy from sellers with good reputations, I´ve purchased XBL memberships from MercadoLibre ( e-bay LatinAmerica ) and never been ripped off. My last purchase was a week ago, 12 mo Live membership for 35 US.
