What is the "Neighbor Trick"

Go in and out of a friends town that has a lot off premium items for an extend period and tap way as normal. U can also tap one house at time when u visit so instead of visiting however many friends u have u triple it by going to tat town 3 times instead of once.

Thanks, I was puzzled about why else I could be doing besides that

i have premium stuff please add. carcher09
