How doi go to shops that are gone on zwinky

I have searched every sight sense i first joined my friend at the valentines store after it had shut donne. No one seems to know the cheat yet, or posted it yet that is. I know the cheat is out there somewhere because ppl somehow get to those stores. I will keep looking, and hopefully the answer will be known soon. For now all you can do is kep looking to see if any of your friends are ever at the closed stores. Join them there and ask around. Someone will have to know how they got there.
