The full price via Stroud is £220.45 and via Any Permitted route is £270.30!
To be honest, at that time in the morning it will be hard to get any really good prices.
It's possible to get to Reading via Worcester and Evesham for a sensible price in the morning (around £50), but once at Reading you're going to have to pay a heap more to come back in the peak. In fact, the best option from Reading is a Thames Branches Day Ranger, but that doesn't have a Family and Friends discount, so would be £43.75. See

Total cost would be around £95
