Buying Kmart cases just to find a Super is not a very good proposition. There is never a guarantee, no matter how many you buy. That being said, I have had some luck when buying two.
I have found three Supers in Kmart cases I ordered online. First was the Datsun 510 Wagon in 2014, next was the Fairlady Z last year, and – not to spoil anything – now this year. So I seem to have luck with the JDM Supers when it comes to Kday.
Then again, I have purchased multiple cases before with no luck. So it is nice if you like the exclusives, just in case no Super shows up. And in the case of this Kmart event, I really like the Fairlady 2000 Roadster. So I was happy with those. But I found the Super anyway. Hooray.
Here is that find, along with showcases of the exclusives, as well as the mail-in. Enjoy.
