I have 2. Not really worth it though it's just another berry juice a day for me. I'm going to need to replace one with a nursery soon anyway. I think you don't get the good stuff until at least rank 8 or 9.
Still working on my shops. My highest ranked shop is just a rank 7 dojo. My avenue itself is only rank 12 and I really want rank 15 so I can get a Nursery up and running.
All my shops are rank 10 except the Nursery. And the Raffle Shop, I always get the Berry Juice, been wondering if its time set. Like if you go at a different time each day you get something new, but no idea.
