At the beginnnig of most events, there is generally a fairly decent low priced gem offer with more than one available in Inventory to purchase. For Atlantis, you have Four that you can purchase, but each one must be a separate purchase. Why not make it so that you can select to purchase all 4 at the same time. The individual purchases trigger the security alert on my CC and I have to contact my Credit card to make the last purchase each time.
Why not make a scroll option so you can purchase 1-4 or simply add a “Purchase all” option? It would help with this as it would go in as one purchase.
