Thanks for that. Wish we'd known too- have also just spent a small fortune there, although most of it was doing price-matching. I wonder whether you can still have the discount combined with a price match- I doubt it.
Sorry to bump this but its worth taking the receipt and asking at customer services if they will honour the discount. We did this with Yeomans when we spent over £800 and out of goodwill they gave us back £80 in vouchers x
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
