We have also been engaged for a little over 2 years. It pretty much depends what the both of you think. We had ours a few weeks ago. Our e-session was included in our photography package. We love how our pictures turned out! It is nice having time before the wedding to get to know your photographer and see if you feel comfortable around them. It is like a little trial run with your photographer. Another plus of e-session...the pictures capture your "everyday look". Totally worth it if it is in your photography package. Good luck deciding.
I would say yay, however, go to jcp or target because they have coupon and nice backgrounds. I only spent 60 bucks plus i have alot of different shots. They are only 3.99 a sheet and they are nice.
