McFirson: Sorry for derailing, but I thought it would be best to ask fellow newsletter discounters.

I've got a problem with the latest code (received in the mail), but I think I know a workaround. Just wanted to share the idea, and if you know the answer, do tell.

I could also make a quick thread to let people know, in case there are similar stories.

I own on GOG Batman: Arkham Knight (base version, funnily enough bought with a newsletter discount).

The redeem page now does not let me to check Arkham Knight Season pass alone. If Arkham Knight: Premium Edition is not selected, Season pass is greyed out and "Redeem" button is not clickable. So without selecting Premium Edition, Season pass cannot be selected as well.

Idea: Selecting both entries, click Redeem and then remove Premium Edition from the cart during the checkout (would lead to code being redeemed, positive or negative outcome for me).
Other idea: Wait, maybe something silly occurred, I will be able to do it tomorrow.

I don't know of some behind-the-scenes reason because of which this wouldn't work, but then again, I didn't come across this issue earlier myself and while googling GOG forums.

POPHASSASSIN: If you redeem newsletter discounters，Accidentally emptying the shopping cart，or Forgot the order，You can redeem again before the code expires，I tried Middle Earth newsletter discounters。（The above is from Machine translation, I can't speak English）
