When you go to buy anything within the battle market there should be an ''are you sure you wish to buy this item'' button that way you dont accidental buy a domination cannon 2 instead of 3 or mistakenly hit something you dont wish to buy.

and a "are you really sure?"... and "are you positive about this?"... etc., etc.
it should go on like this if you keep clicking yes to the previous question..

Whilst trying to buy the mark 2 dominion cannon...

Would you like to buy this item?
(Yes) (No)

Are you sure?
(Yea..) (I ment no!)

You can't get your badges back after
(ok... yea im sure) (made me rethink now... ill leave it for now)

You cannot reverse this process
(ok!) (What! Screw that! ill save em for now)

Are you sure its what you want?
(Yes!!) (Now that you mention it... that mark 3 looks sexy... ill save up for that)

You could save up for the next level dominion... that would be a smart investment for the future
(No i want to buy this Mark now!) (Ok, you win, ill save them up to buy a Mark 3 later)

Is this your final answer?
(OMFG YES!) (No, i take it back)
