Quick answer
Check Costco first
Costco is the first check for high-use bulk products when the household can store and finish the package and the unit-price saving helps justify membership.
Check Target first
Target is the first check for smaller quantities, baby or beauty promotions, easy pickup, and shoppers who do not want a warehouse membership.
Include hidden costs
Compare normalized unit prices, then add membership cost, unused quantity, storage, promotional eligibility, and fulfillment differences.

Source-backed evidence
Current normalized price sample
No compatible Costco and Target category pairs are currently available for the same reference ZIP. Price Scout does not fill that gap with an unsupported winner.
A winner is intentionally withheld until both retailers have compatible, source-backed products for the same market. Run a fresh item-level search when today's cart matters.

Costco
Best for
- Planned bulk purchases and Kirkland Signature products the household uses consistently

- Warehouse, Costco.com, Same-Day, and delivery prices can differ.
Target
Best for
- Flexible package sizes, no required shopping membership, and smaller trips
- Target Circle offers, gift-card promotions, baby, beauty, and household categories
- Drive Up, Order Pickup, shipping, and broad local convenience
Watch-outs
- Some savings require Target Circle activation or a qualifying promotion.

What to compare by category
| Category | Costco angle | Target angle | Scout tip |
|---|---|---|---|
| Paper and cleaning | Costco emphasizes large packs, refills, and Kirkland or national-brand stock-up formats. | Target offers smaller pack choices, up&up alternatives, Circle offers, and household promotions. | Normalize sheets, square feet, loads, fluid ounces, or bags and include only the quantity likely to be used. |
| Diapers and baby | Costco offers large diaper and wipe boxes that can reduce unit cost when the size remains usable. | Target carries more box sizes and frequently uses baby-category Circle or gift-card promotions. | Compare the same diaper size and tier; overbuying before a size change can erase a bulk saving. |
| Groceries | Costco uses a curated bulk assortment with Kirkland Signature and selected national brands. | Target provides smaller grocery packages, Good & Gather products, and easier fill-in trips. | Include spoilage risk and compare equivalent food formats, ingredients, and usable weights. |
| Store brands | Kirkland Signature is central to Costco's member value and bulk assortment. | Target operates multiple owned brands across grocery, household, baby, beauty, and home. | Treat private labels as category alternatives unless specifications are genuinely comparable. |
| Membership and promotions | Costco charges an annual membership, with Executive offering a reward on qualifying purchases. | Target Circle provides account-based offers, while payment-card and same-day benefits are separate. | Annualize membership cost and value rewards conservatively; a future gift card is not the same as an instant discount. |
| Pickup and delivery | Costco provides online, grocery, and Same-Day options, while warehouse pickup is category-dependent. | Target emphasizes Drive Up, Order Pickup, shipping, and same-day options in supported markets. | Channel prices and fees can differ, so compare the exact fulfillment method you will use. |
