Hmmm. Can we make is a 27.5 including shipping? Then I'd get a round number after currency conversion minus shipping. =Dchecking around I can get the individual volumes of just the show for about £16 total so the biggest draw to the complete set is the OVA and compilation film.
I think the most I'd really go for the set including shipping is around £25. It sucks the shipping adds quite a bit to the price, and I understand if this is too low.
