It's still possible to order the non-pewter deck from the Baba store. The only difference is that there is no discount and you'll have to pay for the shipping. The discounted deck cost €15.50 and the current price is €19, so it's still €2 off from the list price.
I agree that things could have been handled differently and that information should have been more clear and available, but what's done is done and we've probably all learned something from this. That said, I really understand the disappointment. I was in the same place myself a few days ago when I realized that all the limited edition bags were gone. These things happen and next time it might be one of us who walks out with a grin while others miss out.
