On 3 September I ordered a few sets of dice from the Paizo store for my gaming group. When I did so, I didn't notice that one of the sets was back-ordered. After placing the order I saw that it would ship in "2 to 45 days".
I then made the mistake of buying some items on 7 September, due to a big sale. Those items, which were all in stock, were on sale and announced because they were running low in stock. I hastily ordered a bunch of items.
I checked in a few days later to see if my items had shipped.
NOPE!
For some ridiculous reason, the new order has been merged with the old order, and even though all items in the new order were available, they would have to potentially wait 45 days to ship.
I attempted to cancel the order, but there is no way to do so without making a call to paizo.
It is now 20 days after the initial order, and many of the items that I ordered are now listed as unavailable. My order appears to be in purgatory, and I can't drop items off the list that are now unavailable to free it up.
WHY?! WHY....
This makes absolutely no sense.
TLDR: Ordered two times, and the new order was automatically merged with an old order that had an item on backorder. The new order won't ship until everything is in stock, and as time ticks by, more items that I ordered are becoming "unavailable" so I will never receive the order.
If you order an in stock item, their inventory system puts one aside for you.
It's an unfortunate thing that your account will show an item as "unavailable" or "back order" when you have a pending order for the last item.
You can ask to have everything currently available shipped now and everything else shipped later.
