For small items, Korea’s convenience-store “half-price” parcels can cut shipping costs. All rates below are from official pages (checked 2026-10-26).

Who this is for

• People selling clothes, books or small items by parcel
• Deals where the buyer is fine picking up at a nearby store

1. GS25 half-price parcel

Based on GS Postbox’s official page.

• Store to store, GS25 → GS25 (some islands excluded).
• Mainland↔mainland, Jeju↔Jeju: up to 500g 1,900 won / 1kg 2,300 won / 5kg 2,700 won
• Jeju↔mainland, mainland→islands: 3,600 / 4,000 / 4,400 won
• Max 5kg, sum of three sides 80cm, item value 500,000 won (500 won surcharge over 300,000 won)
• Prepaid only. Returned if not picked up within 4 days of arrival.

2. CU half-price parcel (알뜰택배)

Based on the CUpost official FAQ and an official Pocket CU notice.

• CU store to CU store, from 1,800 won.
• Max 5kg, sum of three sides 100cm.
• Pocket CU notice rates: 500g 1,800 won / ≤1kg 2,100 won / ≤5kg 2,700 won (island↔mainland 3,500 / 3,800 / 4,400 won)
• Only at stores with a POSTBOX. Very small items, food and document envelopes aren’t accepted.

3. Booking inside the marketplace app

• Danggeun (Karrot): per its official press release (2025-04-10), you can book GS25/CU parcels from the chat. The seller pays via Danggeun Pay, then drops the item at the store. This happens after login, and the seller must have Danggeun Pay.
• Bunjang: per its official guide, book a convenience-store parcel (7-Eleven, GS25, CU, emart24) in the app, then enter the reservation number at the store’s POSTBOX. This also happens after login.

4. Reuse packaging

• Reusing boxes and bubble wrap saves on packing.
• Watch the size limits (GS25 80cm, CU 100cm).
• Remove or cover old shipping labels to hide personal info.

Common mistakes

• Not measuring the box and getting refused
• Not telling the buyer to pick up at a store
• Leaving old labels on reused boxes

Checklist

• ☐ Under 5kg?
• ☐ Sides measured (GS25 80cm / CU 100cm)?
• ☐ Pickup store agreed with the buyer?
• ☐ Old labels removed?
