For more on marking an answer as the "Best Answer", please visit our FAQ.On the faq , it says that oyster is ok to use with the national rail offers if you have a travelcard on your oyster valid for that day, but you must have the Record Card you got at purchase to prove this - you can't just use the oyster on its own. Oyster pre-pay and tube tickets can't be used.
if you only have prepay or don't have your record card I would say to buy a v cheap single train ticket just between 2 stops - there must be some for around the �1-2 mark for stations in london. (remember both people have to have a train ticket to get the 2 for 1)
