I agree with the add a key to the wheel. I also think though that if you are going to allow people paying the 30 US dollars to send the chest you should allow people to have a key cheaper than 30 dollars. That's 31.50 us total revenue for each chest. because you allow each person spending 30 dollars to send up to 20 chests then each person that gets it has to spend the money to get the key. I am a computer programmer. I know it does not cost you 31.50 a chest. Come on now. quit being greedy.
