Congrats on the new Ray gun! Yay! I just got one too. The ammo will appear on top just like cash or a handshake.
I have purchased it yesterday..
so, you will see the bullet on the gun and you must tap to collect (as you were told by the others before), and NO, unfortunately there is no timer, because when you tap it while waiting, the raygun shoots but you don't know how much time you need for the next price.
One notice, DON'T put it in inventory if you plan to move it or redesign, because the counter will reset from 0 when you place it again in your SF.
It looks like you're new here. If you want to get involved, click one of these buttons!
