11st Sibiljeol Sale: The Complete August Coupon and Time Deal Schedule Guide

11st’s August Monthly Sibiljeol runs for 11 days, from August 1 to August 11. This month’s centerpiece is a relay discount coupon worth KRW 3,000 → 4,000 → 5,000 that you can use on purchases of KRW 40,000 or more, which means it’s structured so that working the coupon chain from day one pays off more than waiting for the 11th alone. This article is meant to keep you from thinking “I’ll just buy everything on the 11th” and ending up missing the coupons altogether.

First, Get the August Sibiljeol Dates Right

11st runs its regular “Monthly Sibiljeol” promotion from August 1 to August 11. The name makes it easy to assume it’s just a one-day event on the 11th, but it actually starts on day one — and that’s the starting point for this month’s discount strategy.

With the summer heat and vacation season in mind, this August’s Sibiljeol centers on seasonal appliances like air conditioners and dehumidifiers, along with beauty and cooling products and travel packages. On top of that, popular items go on time deals across categories — water-play gear (rash guards, aqua shoes, tubes), seasonal fruit (gold kiwi, peaches, Aori apples), and easy meals like mul-naengmyeon (cold noodle soup) and bibim makguksu (spicy mixed buckwheat noodles).

Brand-specific events are also split by date: Coca-Cola and Skinfood on the 1st; Chungjungone, Mindbridge, and Catchwell on the 3rd; Carrier, Lotte Wellfood, and SHOOPEN on the 4th; Yuhan-Kimberly and Braun on the 5th; Cuckoo and Happycall on the 6th; and Innisfree and Crocodile Innerwear on the 11th. If there’s a brand you’ve been eyeing, it’s worth setting a reminder for its date.

The Relay Discount Coupons Are This Month’s Real Highlight

The centerpiece of this 11st Sibiljeol sale is its relay-style coupons. You get coupons worth KRW 3,000, 4,000, and 5,000 in sequence — usable on purchases of KRW 40,000 or more — but you have to actually use the coupon you received before the next, bigger coupon unlocks the following day (source: 11st).

In other words, there’s no way to skip straight to the KRW 5,000 coupon. If you have several things to buy, splitting your purchases into KRW 40,000 chunks over several days, rather than buying everything at once, adds up to a bigger total discount. I ran the numbers myself with my cart: paying for KRW 120,000 worth of items in one day gets you just one coupon (KRW 3,000), but spreading it across 3 days gets you KRW 3,000 + 4,000 + 5,000 = KRW 12,000 — as long as you hit the KRW 40,000 minimum each time.

The coupons follow a daily cycle of “claim → use → next coupon unlocks.” If you start late in the event (the 9th–11th), you may run out of time before reaching the KRW 5,000 tier, so if you already know what you want to buy, it pays to get the ball rolling early.


Time Deal Schedule — A Mix of Midnight and 11 PM Drops

Seasonal appliance time deals come in limited quantities, so the time itself is key information. This August’s Sibiljeol mixes in easy-to-miss slots like midnight and 11 PM, not just the usual 7 PM.

While putting this schedule together, the August 1 midnight deal was especially easy to get confused about. On the calendar, it falls right at the moment July 31 turns into August 1 — so if you check in on the evening of August 1, the deal is already over.

There’s Also a Travel Livestream Schedule and a Prize Giveaway

If you’re booking your summer vacation late, the livestream schedule is worth checking too. There’s Jpark Island Resort & Waterpark in Cebu on August 4 at 11 AM, Asan Spavis and Hwasun Aquana on August 7 at 11 AM, and Sono Belle Byeonsan on August 10 at noon. It’s a mix of domestic water-play facilities and overseas resorts, so pick whichever fits your remaining vacation days.

The prize giveaway requires no purchase — just an entry to participate. The prize is a Louis Vuitton “NeoNoe MM” bag worth KRW 3.6 million, and you can enter once a day per ID, up to 11 times over the course of the event. Since more entries mean better odds, it doesn’t hurt to tap the entry button whenever you open the app.

Don’t Forget 11pay (Formerly SK Pay) Rewards When You Check Out

If you only pay attention to the discount coupons, you might overlook the rewards on your payment method. As a reminder, SK Pay points have now been renamed 11pay points, and any points you already had carry over unchanged. If you still think of it as “SK Pay,” just look for 11pay in the app.

  • Paying with 11pay Money: Earn 1% of the payment amount back in points (points expire in 30 days; capped at 20,000 points per member per month)
  • 11st Shinhan Card + 11pay payment: Earn 1% back in 11pay points
  • Other payment methods + 11pay payment: Earn 0.5% back

You can spend your points not just on 11st but also on gifticons, T Direct Shop, T world, and more. Just keep in mind that points expire after 30 days, so rather than letting them pile up and disappear, it’s cleaner to spend them during next month’s Sibiljeol.

Checklist for the Easy-to-Miss Details

  • Confirm the event runs August 1–11 (not just the 11th)
  • Relay coupons need to be used, not just claimed, to unlock the next tier
  • Check that you meet the KRW 40,000 minimum purchase for each coupon
  • The August 1 time deal starts at midnight — set an alarm the night before
  • Prize entries are once a day, up to 11 total — you can’t do them all in one day
  • Check the 11pay reward rate before choosing your payment method
  • Seasonal appliances have limited stock — check installation fees and delivery schedule on the product page

Time deal items are available in limited quantities per time slot and can sell out shortly after they go live. It’s safer to double-check the final price and remaining stock on the event page right before you check out.


Frequently Asked Questions (FAQ)

If I skip a day in the middle of the relay coupons, do I have to start over?

The coupons work so that using the previous tier’s coupon is what unlocks the next, larger coupon the following day. If you let a day pass without using it, you won’t move up to the next tier, so it’s best to plan your purchases early in the event.

What’s the difference between the Monthly Sibiljeol and the Grand Sibiljeol?

The Monthly Sibiljeol is a regular promotion held every month, and August’s event falls under this. The largest event is the Grand Sibiljeol, held every May and November, so for expensive items you’re not in a rush to buy, waiting until November is also an option.

My SK Pay points seem to have disappeared — where did they go?

They haven’t disappeared — they’ve simply been renamed 11pay points. Any points you already had are still there; only the brand name changed.

Is it too late to buy an air conditioner in the time deals?

There’s an LG Whisen AI Objet Collection View II Air Conditioner 2-in-1 time deal scheduled for August 10 at 7 PM. Since it’s late-season stock being released, it’s worth considering price-wise, as long as you can allow extra time for installation scheduling.


To sum up, if you keep just two things in mind for this 11st Sibiljeol sale — the early coupon chain and the nighttime time deals — the discount you actually feel adds up quite differently. Start by splitting your cart into KRW 40,000 chunks in advance, and set alarms for the dates of any brands you’re interested in.
