Mrs. Kim and most likely Mr. Kim. The store is filled with all kinds of old antique items with rich pasts. Mrs. Kim always manages to throw in some historical detail about an item that a customer may be looking at.
Lane works at the store with her mother. When she attempts to get a sale, she does creep behind her customers like her mother. Although in one episode she does show a little [Kim] in her sales pitch.
"You brake you buy!" is [Kim]'s famous logo.
The store is in part of the Kim house. The living room and kitchen are both located on the first floor with the shop. Lane's bedroom, along with [Kim]'s bedroom, are located on the second floor. There may be other bedrooms, although the upstairs was never shown in great detail.
