Sample Smelt Different...

I don't know if anyone else has the same issue I did a few weeks ago: got a sample fragrance, fell in love, and purchased the full bottle. For me, it was Killian Paris' Angel's Share. The full bottle smells very little like the sample. I feel a little duped, because I desperately just want more of whatever was sent to me in the sample. Is there a chance the formula changed in the in-between?

 

I can't return the full bottle either (friend got it with no return receipt, don't even know the store it was from) so I don't know what to do with it. Any ideas?
