There was an issue over the weekend with the Galactic Upgrade Kit having the incorrect price listed on the Android store. The price on Android will be updated to the correct amount of $7.99 shortly. Also, it should be noted that the pack description is incorrect. The pack is only purchasable once in the period of time it is offered, not once per day. Apologies for any confusion.
We will not be issuing a refund for the differential. If the error had resulted in an increase to the price, we would refund those players, however since it was a discount, we will not be providing any compensation.
As a reminder, we do not do any sort of price testing such as showing one group of players one price and another group a different price. This was an error.
