Yes, but it won't be unlocked until it reaches the in-store word-of-mouth level.

5 stores with 8 mouths, 6 stores with 7 mouths to unlock clothes.

6 branch 8 kou unlocking electrics

Grade, basically word of mouth, grade is definitely enough.

I didn't unlock it. You can only see clothes and electrical appliances in the shop, but you can't see any goods.
