Labels: [Sourced] checked against a source listed at the end. [General] standard industry knowledge. [Our view] opinion, labelled as such. [Illustrative] made-up numbers to teach an idea.

1. The story: Target's parking-lot experiment

Target first partnered with San Francisco-based Curbside in 2014, testing pick-up in parking lots at 11 Bay Area stores. In October 2017 it was testing "Drive Up" in 50 Minnesota stores, trailing Wal-Mart. [Sourced: CNBC, Oct 3 2017] By August 30, 2019, Drive Up was in all 50 states and reached 1,750 stores, less than two years after launch. [Sourced: Retail Dive] The store, which looked like a cost, became a tiny warehouse and pickup point. [Our view]

2. The one idea

Shoppers don't think in channels. They want to browse in one place, buy in another and return in a third. Omnichannel means one inventory, one customer, one price story across every door. [General]

3. The kitchen-table version

Your bank: app, branch, ATM. Same account, same balance everywhere. When one door shows a different balance, you stop trusting it.

4. The common services [General]

Ship to home, ship from store, buy online pick up in store (BOPIS), curbside, returns in store, endless aisle (order in store for home delivery).

5. Why it is hard

  • You need one view of stock (Modules 3, 9). If online shows 4 but the store has 0, the order fails.
  • Fulfillment choice matters for cost (Modules 8, 12).
  • Returns cross channels (Module 12B).

6. How big is online?

US retail e-commerce sales in Q2 2026 were estimated at $340.2 billion, seasonally adjusted, out of $1,986.5 billion in total retail sales, about 17% (17.1% when we divide; FRED lists 17.1%). The Census Bureau notes these estimates will be revised with the Q3 2026 release on November 19, 2026, so treat the share as "about 17%". [Sourced: US Census Bureau, Aug 18, 2026 and its Sept 28, 2026 notice; FRED] So most retail still happens in stores, which is why stores matter to online strategy. [Our view]

7. Worked example: pickup versus delivery [Illustrative]

An order of $60 with $22 gross margin. Delivered to home: fulfillment cost $9, leaves $13. Customer picks up in store: cost $2, leaves $20, plus a chance of an extra purchase in store. Pickup earns $7 more (9 minus 2). The numbers are made up, but the direction is why retailers push pickup. [Our view]

8. Where AI fits

Choosing which node fulfills each order; predicting pickup demand by hour; reading intent across channels; assistants that shop across stores (Module 21). [General]

9. Exercise
