We compared Costco and Jet prices to see which company offers better deals. Here's the verdict. (COST, WMT)

• Costco and Walmart-owned Jet.comsell just about everything.
• Both stores sell in bulk, offer free two-day shipping with membership, and carry inexpensive private-label products.
• We compared prices across a few categories at both stores and found Costco was generally less expensive. Here's how they stack up.

The two companies have a lot in common, including two-day delivery on online orders and selling essentials in bulk quantities.

While Costco requires a membership to shop in its stores, it doesn't require one to shop online. The retail giant is well-loved by customers, and its website offers many similar deals to its stores. For shoppers who do hold a Costco membership, the warehouse club offers free two-day shipping for many essentials and same-day delivery for groceries. The website also has plenty of products from Costco's beloved private-label brand Kirkland Signature.

But Jet has been making strides to compete with Costco, like offering daily deals and free two-day shipping without membership fees. Though Jet can't compete with Costco's physical presence, it offers JetCash, which are rewards incentives that can be used as cash on the site. It also has a private-label brand called Uniquely J, which is designed to attract millennials by creating environmentally friendly products in artist-designed packaging.

Even though products are sometimes listed in different quantities or under different categories, the websites have a huge overlap in what they sell. To see which of the two stores had better deals and was more user-friendly, we compared common items from different categories on each site to see which had better deals.
