You are totally right: sorry about the botter.
If you go to the asset page the full price (in dollar$) shows next ot the "Buy it" button (at least in the spanish version, it may be a fumbling with translations strings on itch.io). But when you click on it and the preview page with the price, the VAT taxes to add, and the total appears (still in dollar$), it does show the discounted price. Of course then Paypal shows finally the price (in €uros).
Still, showing three different prices in two different currencies and the lack of a shopping cart to buy several things at the same time only proves one thing: the shopping engine sucks! -_-U Sorry abouth the mini-rant, but things like that confusing the waters only make small creators like you trouble and lost sales.
Anyway, I wish you good luck with your health issues. While I am *mostly* well, there had been plenty of people with those in my circle of family and friends, so I hope things get better for you. Regaining some health stability and physical autonomy can do a world of good for anyone's mood, so cheers!
