Are there any broad catalog online shops that focus on browsing product selection across many departments?

Yes — there are several broad, catalog-style online shops that are good for browsing across many departments rather than specializing in one category. Common examples include:

• Amazon — the largest broad catalog marketplace for just about everything
• Walmart.com — general merchandise, groceries, household, electronics, etc.
• Target.com — home, apparel, beauty, electronics, kids, and more
• eBay — broad marketplace with new, used, and collectible items
• Best Buy — broader than electronics alone, but still mainly tech-focused
• Wayfair — broad home/furniture/decor catalog
• Macy’s / Kohl’s / Nordstrom — department-store style browsing across many consumer categories
• Costco.com — broad but more limited if you’re not a member

If you mean sites that feel like a traditional department store online, Target, Macy’s, Kohl’s, and Walmart are probably closest. If you mean massive marketplace catalogs, Amazon and eBay are the main ones.

If you want, I can also give you:

1. the best ones by category (home, clothing, electronics, etc.), or
2. the best websites for browsing without much searching.
