Immediately after a successful purchase you can see all items that are being credited to your account. Also, a message with all items purchased appears in your Journal. This means that all items of that package have been added to your account.

Certain items' location, however, may not be as obvious. Note that such items as Dragon coin chests, as well as craft material or enchant chests, are credited to your "Items" interface and can be found in "Miscellaneous" and "Chests" sections respectively.

If a purchased package contained an item that activated a certain effect, e.g. Premium or Total Development, then the effect will activate immediately after the purchase (don't forget to activate the Premium title manually though). If you can't see the effect immediately after the purchase, please refresh the page.
