TL;DR: This comparison review shows AliExpress costs 30-70% less than Coupang but takes weeks longer for delivery - buy recommendation depends on urgency needs.

If you shop online in Korea, you've probably wondered: should I just buy it on AliExpress for half the price? Or is Coupang's convenience worth the premium? The answer isn't always obvious, so let's break it down category by category.

How much cheaper is one than the other?

On average, AliExpress is 30~70% cheaper for the same product. The difference is most dramatic for small electronics, accessories, and cables.

Some real examples:

  • USB-C hub: Coupang ₩25,000~40,000 vs AliExpress ₩8,000~15,000
  • Wireless earbuds: Coupang ₩30,000~50,000 vs AliExpress ₩10,000~25,000
  • LED strip lights: Coupang ₩15,000~25,000 vs AliExpress ₩5,000~12,000
  • Digital kitchen scale: Coupang ₩12,000~20,000 vs AliExpress ₩4,000~8,000

That said, Coupang's own private-label products and sale events can close the gap significantly. It's not always a clear win for AliExpress.

How long will shipping take?

Coupang's killer advantage is Rocket Delivery. Order before midnight, get it tomorrow. For urgent purchases, nothing beats it.

AliExpress "Choice" items take 7~15 days to Korea. Standard shipping runs 2~4 weeks. In 2026, AliExpress has set up Korea-dedicated fulfillment centers, which has improved things — but it's still not next-day.

Bottom line: if you need it now, Coupang wins. If you can wait, AliExpress saves money.

Is the quality actually the same?

Here's something many people don't realize: a huge number of products on Coupang come from the exact same OEM factories as AliExpress items. Different brand sticker, same product underneath. This is especially true for:

  • Cables, chargers, adapters
  • LED lights and strips
  • Small kitchen tools (scales, peelers, grinders)
  • Phone cases and screen protectors

Where Coupang genuinely offers better quality:

  • Fresh food and groceries (cold chain logistics)
  • Large appliances (installation and after-sales service)
  • Brand-name products (lower counterfeit risk)

What happens when I need a refund?

Coupang makes returns effortless. Rocket Delivery items get free returns within 30 days — a courier picks it up from your door. This convenience is hard to beat.

AliExpress has improved its return policies, but international returns can cost more than the product itself. For low-value items, sellers often just refund you and let you keep the product. For expensive items, the return process can be frustrating.

Will I have to pay customs fees?

Orders over $150 (about ₩200,000) from AliExpress trigger Korean customs duties — roughly 10~20% on top of the product price. Many first-time buyers get surprised by this at customs clearance.

Coupang is domestic, so no customs worries.

Tip: split large AliExpress orders to stay under $150 per shipment.

Which platform should I choose when?

Choose AliExpress when:

  • You're not in a rush for small gadgets and accessories
  • The product is 2x+ more expensive on Coupang
  • You want niche items not available domestically
  • You're okay with some trial and error

Choose Coupang when:

  • You need it by tomorrow
  • You're buying food, groceries, or household essentials
  • Easy returns matter (expensive or uncertain purchases)
  • Brand authenticity is important

What's the best way to shop smart?

The best approach is using both platforms strategically:

  1. Check the price on Coupang first
  2. Search for the same product on AliExpress
  3. If AliExpress is 30%+ cheaper and you're not in a hurry, order there
  4. If the price difference is small or you need it fast, go with Coupang

Regardless of platform, always check reviews. On AliExpress, review photos are your best friend — they show the real product far better than listing images.
