Just got an email with this offer.
I just upgraded to an Xbox One X recently and this looks like a good deal to me.
Terms thanks to star64 :
Xbox One X trade offer: EB Trade policy applies. Console must be working and complete. 2 games refer to Xbox One games, must be in resalable condition. Cannot be combined with any other offers. Offer expires 22 Sept 2018. Strictly while stocks last. See staff for details.
According to some users and to EB Games on Twitter, you can also trade in an original Xbox One X. Contact your local store and depending on the size of the hard drive in the console, EB Games will give you a similar deal but for a higher price.

Probably too late now. They had a pretty good deal about two years back. Traded my original One towards a One S + Battlefield 1 + an UHD Movie and I think all up I was about $120 - $150 out of pocket after they factored in my Level 4 memberships extra 30% trade value. Also didn't have to trade any games in.
Not sure anyones jumping to get original consoles at this time.
