how much was it going for??
I also have a bottle of the EDP but I have also had experience with EDT.
I think one of the main differences is that the EDT has less bergamot/citrus going on and more wood/etc. It comes off as lighter, maybe even sweeter. They are pretty similar but it is a difference, I love the EDP but I also love the EDT so I might just have to swing by my local T.J. Maxx . . .
