Earlier model
This guide concerns earlier Offer Room records. Use the Offer Market guide for the new private offer flow.
Listing and plan
Use an eligible published listing and qualifying Pro, Premium or Exclusive access. Room level, listing market, starting range and active restriction are validated server-side.
Included balance and capacity
Pro includes one Tier 1 opening each month; Premium includes two Tier 1 and one Tier 2 opening. Each tier balance is consumed separately. Active capacity is the number of rooms that may remain live at once and never replaces those balances.
Seven levels and plan access
Pro can open Levels 1–3, Premium Levels 1–5 and verified Exclusive accounts Levels 1–7. Levels 6–7 are reserved for high-value, live listings with a clean review state. The buyer entry price and seller opening price are shown separately; the seller opening is exactly twice the entry price.
Changing a live room
Before paid participation you may prepare another permitted level. The current room stays live through the 30-minute checkout and changes only after the exact payment or included right is verified. An expired checkout or listing drift goes to review; it does not silently close the current room.
Before publication
Review the starting offer, pace, duration, entry disclosure and object-sale boundary. Opening payment, when required, is a separate Collectorium digital service.
