While I’m sure you’d love it if I said ‘Absolutely’, unfortunately you’re going to be a bit disappointed. No matter how much you want the answer to be ‘Yes’, the answer is ‘No’. You only get one Scratch-R card every 6 hours, no matter how many Kwik-E-Mart’s your Springfield is currently While initially Itchy and Scratchy will appear over all of the Kwik-E-Marts in you town, as soon as you’ve played one the Scratch-R icon disappears from all of them.
However, having more than one Kwik-E-Mart is still a good idea. It helps your consumerism (on your Conform-O-Meter) reach 5 Stars, which is extremely important if you’re looking to get the maximum Conform-O-Meter bonus. And in the end the Conform-o-meter bonus-multiplier could be worth much more than the Scratch-R pay out.
