Why it matters. It shows how global inflation shocks reach ordinary consumers in one of Asia's biggest economies, and how retailers respond with deflation-style pricing tactics worth watching elsewhere.
Background. 'PB' (private brand) is the common Korean term for retailer-owned store brands. South Korea has three dominant hypermarket chains — Lotte Mart, E-Mart and Home Plus — and the country's household size is shrinking fast, with single- and two-person homes now the majority, reshaping how groceries are packaged and priced. The won trades at roughly 1,400 to the US dollar.
What to watch next. Expect the chains to keep widening their ultra-cheap ranges and small-pack lines if Middle East-driven cost pressures persist.
Cheap by design
South Korea’s largest supermarket chains are flooding their shelves with ultra-cheap house-brand goods priced at or below 1,000 won (roughly $0.70), the retailers said this week, as accelerating inflation tied to instability in the Middle East squeezes household grocery budgets. The move is aimed at retaining cost-conscious shoppers and courting the country’s fast-growing number of one- and two-person households.
So-called private-brand (PB) products — store-owned labels that cut out third-party manufacturers’ margins — have become the chains’ main weapon against rising prices. The strategy lets retailers hold quality steady while pushing costs down, an industry official said, even as raw-material expenses climb.
Lotte Mart doubles its budget range
Lotte Mart, one of Korea’s top hypermarket operators, has expanded its sub-1,000-won lineup from about 45 products in 2024 to 90 as of June 2026, broadening from fresh food, drinks and snacks into household goods. Sales of those items rose 18.3% year-on-year between January and June 8.
Under its “Oneul Joeun” (“Good Today”) label, popular sellers include:
- 1,000-won soybean sprouts and tofu (300g each)
- 500-won strawberry, banana and chocolate milk (200ml)
- 1,000-won three-ply tissues, mini pocket tissues and wet wipes
The chain planned to add 980-won mung bean sprouts (380g) on June 11 and 690-won soft tofu (350g) on June 25.
Rivals follow with small-pack and snack deals
E-Mart, the country’s biggest discount-store chain, launched “Sosohan Haru” (“A Small Day”), a private brand of small-portion fresh produce designed for smaller households. Best-sellers sit in the 1,000-won range: 990-won mini peppers (80g), 1,480-won new-season onions (240g), 1,980-won green onions (200g) and 1,780-won peeled garlic (80g).
Home Plus, another major chain, ran a discount event on its “Simplus” label from June 11 to 17, selling americano, sweet americano and caffe latte coffees at 1,000 won each and various corn and chip snacks at 1,990 won.
The pricing reflects a broader belt-tightening across Korean retail. By concentrating volume in a handful of staple items and stripping out branding costs, the chains are betting that visibly cheap basics will keep shoppers walking through their doors rather than turning to discount grocers or online sellers.
