Two ideas for purchasing stuff:
If there are multiple items in stock, please add a quantity button. It is a pain when you get those specials for $1.99 and it says 4 or 5 in stock and you have to go thru multiple transactions if you are purchasing more than one. You this available for using loot tickets. Why not here?
For special offer events, like the Christmas/Advent Calendar: can you possibly allow a purchase price in both cash and gems, please? Seems it would easier on the players and might increase sales. I know in the past I got a play card and faced with do I hold onto the credit amount to see if there is a good offer coming up or go ahead and purchase the best pack of gems? Either way, you’re making money and it might help some players whose significant other keeps them on a gaming allowance (or so I’ve heard) be able to purchase more things. In the end, you still make money!!!
