Replying to Should i go for the good karma?

so basically, i wanted to have an new subscription on an dutch freeski magazine, and my good friend toonoman wanted a new goggle.

so if you were an new member to the freeski magazine you could choose to get a gift, and we choose to have the magazine and a new goggle for 35 euros extra.

now the thing is we wanted to have that goggle asap because we were leaving on a trip to france 1 week later. so the people from the magazine sended the goggle out asap and were pretty damn friendly to help us and the goggle was delivered in time.

15 minutes ago there was an package delivered for me, and in that package is now another goggle!
clearly its a mistake from the magazine, but should i send it back? or should i keep it?
