I would agree with Kanazawa-san's answer if the question was asking about goods, but this term is describing a store *classification*, not what is being sold in the store per se.
Further, according to the definition of "Miscellaneous Store" in the link provided by Kanazawa-san:

453 Miscellaneous Store Retailers
Industries in the Miscellaneous Store Retailers subsector retail merchandise from fixed point-of-sale locations (except new or used motor vehicles and parts; new furniture and house furnishings; new appliances and electronic products; new building materials; and garden equipment and supplies; food and beverages; health and personal care goods; gasoline; new clothing and accessories; and new sporting goods, hobby goods, books, and music). Establishments in this subsector include stores with unique characteristics like florists, used merchandise stores, and pet and pet supply stores as well as other store retailers.
So in this instance, perhaps the "その他(の)" definition would be closer to what you need than 雑~. HTH a little...
