Features
For buyers and for sellers, grouped the way you use it. Each feature says what it does in one line, and what protects you is spelled out with real numbers.
From the screenshot of something you want to the parcel at your door: every step, and what protects you at each one.
Know if a price is good before you commit.
Prices from other shops for the exact model and variant, with shipping included.

A reference price from trusted independent sources, so you know what the group should aim for.
Sellers compete for the whole group instead of one shopper.
Set the most you would pay. It is a hard limit: you are never charged above it.
A negotiator agent speaks for the group, round by round, in a live room.
Join Blocs that verified sellers opened for new products, before anyone else asks.

A hold, not a charge, until there is a deal.

An email when someone signs in from a device you have not used, and a log of activity.
An inbox for wins, shipments, refunds and replies; emails for anything about money or deadlines.
OpenItems marked demo stand-in run as clearly labelled simulators in this prototype (PayPal sandbox simulator, carrier tracking, identity checks, and a replay in place of the language model) until each provider's keys are configured. Nothing is hidden: the same code paths run either way.
