I've bought advance train tickets from Virgin Trains on many occasions and a couple of times I've had to change my time of travel -which costs you a £10 admin fee (plus the price difference if it's a more expensive ticket).
This time, I bought my advance tickets (knowing that there was a possibility I might want to change the time of my outward journey) and at the end of the process it now has e-tickets as the automatic selection for method of delivery, lists it as the recommended option, with a list of the advantages of doing so and then further information on how it works in practice. There are no other links provided in this section with any further details about any differences between this and paper tickets.
Once you have bought the ticket however, you are informed that, unlike paper tickets, e-tickets are non-refundable and if you want to change your time of travel you just have to pay full price for a new ticket.
AIBU to not have known this and AIBU to think Virgin should state this on the page where you select the type of ticket you want because the page purports to list the pro's and cons and practicalities of these types of tickets but misses off one very important one ie that for the same price you are getting a much worse deal if you get an e-ticket and could end up significantly worse off if you need to change your time of travel?
