Costco Korea: July Week-Three Basket and Package Comparisons
A grocery basket mixes different units: an egg count, an eggplant count, a litre of spirits, and packages with no weight. This historical record can illustrate those differences without being presented as a live discount list.

Which comparisons are supported?
The seven eggplants at 3,890 KRW work out to about 556 KRW each. The 30 eggs at 10,490 KRW work out to about 350 KRW each. Both calculations retain the units actually listed. The beef-shank packages have different totals and no captured weights, so their per-kilogram value cannot be compared from these numbers alone.
The source says a 4,000 KRW package discount applied to the beef and describes sharing some produce with family. Those details help explain the basket size; they do not establish a present-day offer or a suitable quantity for every household.
Planning ingredients across dishes
Eggplant, tofu, onions, eggs, and seaweed serve different parts of a home-cooking plan. Before copying a basket, distinguish ingredients that can be distributed across several planned dishes from packages bought for one specific meal. Package count and household use are more informative than adding every historical bargain to a shopping list.
