On the match information page they're listing:

Season Ticket holders use voucher 4 to get a friend in for £10
40% discount in the shop
Full catering options expected

That's on top of the £15 ticket offer that was emailed round (let me know if you want a copy)

"Please, please, come to the match and watch us. We know it might be wet, the match is on TV, and the team looked shocking on Saturday, but please still come along"

I jest of course. Frankly, this is all the right stuff they should be doing - trying to keep people coming through the gate and getting some support in. They've moved fairly quickly which is good.

Don't they flog the stuff off at end of every season
Then next season fleece us with the new range (around end of June)

EDITED for accuracy.

Fair point well put!
