The tickets come in batches of 25, 50 and 100. These are priced £25, £50 and £100 respectively. I’m sure you can work out that means entrance is therefore reduced to £1 per visit. You can buy tickets from the entrance kiosk, but if you present your TAS membership at the Aviation Shop on site, you’ll get 10% off the ticket cost.

There’s no mention whether the tickets are for pedestrians only, or include car entrance. Perhaps someone could comment if they know.
