You remind me of myself; we can, if allowed, overthink things to death!
If you don't mind, I'll weigh in here. I don't think you should have to talk yourself into the bag. You'll always resent that it wasn't what you dreamed of. I'm only saying this because in every single post you've mentioned how much you wanted this combo and how you were so excited for it. If you settle, you'll always
feel like you settled and the bag will lose its sparkle.
Either get a refund or see if Marco can order only 1 skin (I can't find the quote but you did say he's looking into that).
If you miss out on this particular combo, it's fine. There will be others you will get just as excited about, I assure you! You may recall that we've all discussed this on the editing thread: there's always another stunner. If this one isn't meant to be yours, it's only because a different one that is even more perfect is around the corner.
Another option is to get the bag you ordered but swap the green for another metallic, so that you're not missing out on all 3 colours from the original order. And then if the green comes up in the future, you can buy something else in that leather.
Good luck with your decision.
