Any discounts for Leeds Castle?

The tickets are so expensive (appreciate they're valid for 12 months but we're just camping locally and so won't be back again). I've seen the Visit Kent 2 for 1 that you can use with a train ticket but it says:

"Train tickets should be a min of £10 each" - so I'd be paying £20 for 2 rail tickets(that we don't need) to save £24.50 and have the hassle of trekking to a station to purchase a ticket so not worth it.

Seems a shame to be so close and not visit but £180+ for 6 adults and two 4 year olds is a very expensive day out. Any advice appreciated. Thanks
