The Meetup Problem

Abstract

Peer-to-peer commerce has become ordinary. The handoff has not. Almost every local sale still ends with two strangers agreeing to occupy the same square of pavement at the same minute, and the public remedy for that, a marked parking space outside a police station, is open fewer hours than most people work and unavailable to many of the people who need it most. In July 2026 the Postal Service began selling an alternative, which makes the design question concrete rather than hypothetical. This report sets out what is actually exchanged, what goes wrong, what nobody counts, and what changes when a handoff no longer requires two people to be in one place at one time.

Findings

1. 01

   Local, in-person resale is mainstream behavior rather than a niche. 93 percent of Americans bought a secondhand item in the past year and 54 percent sold one, per the 2025 OfferUp survey with GlobalData.

2. 02

   There is no national count of harm at meetups. No federal crime series records whether a robbery, assault or homicide began as an online listing, so policy responds to individual deaths reported locally rather than to a measured trend.

3. 03

   The main public remedy is small, supervised by nobody, and mostly a weekday service. Across ten US jurisdictions reviewed, six recommend or effectively limit use to weekday business hours, and every program that addresses the question states that officers will not observe the exchange.

4. 04

   A marked space at a police station is not a neutral place for everyone. More than a decade of survey and clinical research finds substantial shares of Latino residents, including US-born ones, who avoid contact with police out of immigration-related fear.

5. 05

   Even when nothing goes wrong, the meetup itself is the friction. Two schedules have to converge on one place and one moment, and the cost of that is roughly the same whether the item is worth thirty dollars or three hundred.

6. 06

   Most of the volume is small items and most of the value is a few large ones. Phones, clothing, jewelry and household goods fit in a compartment; furniture and vehicles do not, and private-party sales were 42.2 percent of US used-vehicle transactions in 2025.

7. 07

   A national asynchronous option now exists and its constraint is density. USPS Local XChange launched on 15 July 2026 at $5.51 per item, resting on the roughly 700 post offices that had the compartments as of October 2025.
