Can you recommend broad online retail sites for a busy household buyer who wants mixed categories and easy returns?

Yes — for a busy household buyer who wants lots of categories in one place and simple returns, these are strong options:

Best broad online retail sites

1. Amazon

   • Huge selection: household, groceries, electronics, clothing, toys, basics
   • Very convenient delivery options
   • Returns are generally easy, often with drop-off locations

2. Walmart

   • Good mix of everyday essentials, groceries, home goods, electronics, and kids’ items
   • Strong pickup/delivery network
   • Returns are usually straightforward, especially through stores

3. Target

   • Great for home, pantry, kids, personal care, clothing, and seasonal items
   • Easy in-store and online returns
   • Good for household buyers who want a curated but broad assortment

4. Costco

   • Best if you buy in bulk and want household staples, pantry items, and larger goods
   • Returns are famously customer-friendly
   • Membership required

5. Kohl’s

   • Broad enough for apparel, home, beauty, and gifts
   • Easy returns, especially in store
   • Often useful if you shop sales and want flexible return handling

6. Wayfair

   • Best for home goods, furniture, decor, and organization
   • Returns are generally manageable, though not always as simple as Amazon/Target
   • Great if “mixed categories” leans heavily toward home-related purchases
