The short answer
The Marketplace is useful when it answers a specific shop need: a part for an active repair, a device you can refurbish, or a donor device likely to improve your spare-parts inventory. It becomes risky when “cheap” is the only reason to buy.
Before every purchase, confirm four things:
- What job or inventory gap does this purchase solve?
- Can your current licenses and tools process it?
- How much cash remains after the purchase?
- Is the possible result worth the uncertainty?
Step by step
1. Start with the job, not the listing
Open the Notebook or active order first and identify the part or device category you actually need. This keeps Marketplace browsing tied to a repair outcome instead of turning it into speculative inventory collecting.
2. Classify the listing before buying
Place a Marketplace purchase into one of three buckets:
| Purchase goal | What you plan to do | Main risk |
|---|---|---|
| Needed part or device | Finish a known active order | Compatibility or hidden additional damage |
| Refurbishment | Repair and resell a complete device | Parts and labor cost exceed the result |
| Donor device | Disassemble for reusable components | Useful contents are not guaranteed |
If you cannot name the bucket, keep the cash.
3. Protect the shop’s operating money
Marketplace purchases compete with licenses, replacement parts, and tool upgrades. Do not spend the cash reserved for an accepted email order. A potentially useful donor device is less valuable than completing a job already on a deadline.
4. Inspect and sort the result
When a purchased device reaches the bench, disassemble it through the normal repair workflow and classify each component by its visible game state:
- Usable: move it to the spare-parts inventory.
- Dirty but serviceable: clean it before storage or use.
- Broken: isolate it for shredding once that tool is available.
Do not treat every old or removed part as broken.
5. Build a small, useful inventory
The purpose of spare inventory is to keep real repairs moving. Retain parts that match the kinds of devices currently entering the shop, then reassess. A large pile of unrelated components ties up money and makes useful stock harder to see.
Marketplace or online order?
These systems solve different shop goals:
| Route | What you commit | Best fit | Main risk |
|---|---|---|---|
| Online order | Time, delivery, and a deadline | You already have the likely license, tools, cash, and capacity | An unknown part or delay turns the job into an obligation you cannot close |
| Marketplace refurbishment | Cash upfront and repair effort | A device fits current capabilities and has a clear resale purpose | Total repair cost exceeds the result |
| Marketplace donor | Cash upfront for uncertain components | You can name the inventory gap the donor may fill | Useful contents are not guaranteed |
Use the email order guide when the question is whether to accept work. Stay on this page when the question is whether to spend cash on stock.
When to stop buying
Leave the Marketplace when:
- the purchase would consume money needed for an accepted repair;
- you cannot process the device with current licenses or tools;
- your inventory already contains the needed component;
- you are buying only because a listing looks inexpensive;
- the expected value depends on a random result being guaranteed.
This stop rule is more useful than an unverified list of “always buy” items.
What not to assume
- Marketplace stock or prices follow a fixed schedule.
- A parts box has guaranteed contents or profit.
- Every cheap device is a good donor.
- A single observed purchase represents the game’s overall probabilities.
- Marketplace profit cannot be compared with online-order profit through an unverified fixed formula.
