Alton Towers - 2 for 1 vouchers on any yoghurts / cereal boxes?

[Crackery]

Wonder if MN can direct me. I often see Alton Towers 2 for 1 vouchers on different food packages etc. Are there any around just now... planning a trip this autumn.

TIA

Carex handwash has half price entry on it.

Multipack freddo chocolate bars have them

Thanks!
