1. Book review queue

Tick one or more approved books, then click Export selected to 3Dsellers CSV. Export uses the official 3Dsellers 79-column CSV; original full front and rear scans are used without promotional borders or logos. Images are prepared as cropped listing-only copies and hosted automatically. Import promptly and review the draft. No bulk re-import during testing.

Listing Test Centre — 3Dsellers / eBay UK

Select approved books above and run checks before exporting. This tests the exported values and photos, not eBay's remote acceptance. Missing information or overly long image links will stop export.

Policy IDs are eBay/3Dsellers numeric IDs, not postal charges. Your browser remembers them. Check the dispatch postcode before exporting.

Automatic listing-image hosting

Approved books can publish separate listing-only photo copies to the public listing-images bucket. Original scans remain private. Click Prepare listing images; saved public URLs are stable and used for export. Manual short links remain a fallback.

2. Upload book scans

Choose the original front and rear JPEGs from your Mac. Originals are stored privately in Supabase. The rear scan is the best place to read an ISBN.

Front cover (JPG / PNG)

Rear cover (JPG / PNG)

Text recognition runs in your browser and may take time on the first use. It suggests text; always check the edition. No automatic crop is applied to original scans.

Open a book with Edit, then select “Identify & Research Book”. You can also use newly selected scan files.

Your selling price (£)

Enter a price, then press Save price to inventory. Existing approval and stock ID will be retained.

4. Measurements & automatic postage

Check the book measurements; ResellerRobot recommends the D/1 or E/2 envelope and Royal Mail 2nd Class Click & Drop price. You do not have to choose a postal class. Estimated package dimensions are calculated as book length, width and thickness + 4 mm each. Check the actual packed item using your 25 mm slot; weigh before buying a label.

Enter measurements to see automatic Royal Mail postage.

Catalogue estimates are placed directly into empty boxes for you to check and edit. Your saved measurements take priority.

Packaging dimensions are estimated as the book dimensions plus 4 mm on each axis. Your 25 mm slot decides whether the sealed package actually qualifies. Weight must still include the real book and packaging; do not use 1–3 g as the total packed weight.

Packaging — The Reuse Club

D/1 and E/2 are selected automatically from external dimensions, allowing some clearance. Empty weights: 1 g and 2 g (editable). The finished package determines the final postage service. For eBay export, physically weigh the book and the finished package; a 1–3 g envelope is NOT the packed weight.

Suggested envelope (change only if needed)

Empty envelope weight (g) — editable

Estimated packed thickness (cm) — book + 0.4 cm

Packed weight (g) — automatically book + 4 g; editable if weighed

Choose D/1 or E/2 to see fit guidance. Packaging selections are saved in this browser only, not yet included in eBay CSV.

Approve a saved item to assign a permanent stock number and print an 89 × 35 mm label. Saving a draft does not use a number. Print from your Mac with DYMO LabelWriter 450 selected. Stock ID will be exported as the eBay Custom label (SKU).

Automatic Mac scan arrivals

For hands-free uploading, run the ResellerRobot Mac helper. It creates new entries in the Review Queue above as each front/rear pair arrives. Click Refresh inventory to see the new arrivals. Newly arrived books are automatically checked for ISBNs while this page is open; any results require your review. The manual batch uploader remains available as a backup.

Automatic ISBN lookup is available for new scans. Your existing edits and measurements are preserved.

Manual batch upload (backup)

Choose the scanned JPEG files together (you can select all in Finder). Odd scan numbers are fronts and the next even number is the back. Review every pair before saving. This does not watch the Mac folder in the background.

Select scanned images
Choose Scan 1.jpeg, Scan 2.jpeg, and so on. Missing, repeated or unnumbered files will be flagged.
