1. What does it mean?
핫딜 borrows hot deal. It labels a sale or offer that someone considers unusually appealing, commonly because of the price, included extras, or limited availability.
Also written or said as hatdil
2. The nuance
It is a promotional or community judgment, not proof of the lowest price. Shipping, options, conditions, and the normal selling price can change whether an offer is actually good.
3. Examples
“핫딜 글을 보고 배송비까지 확인했어.”
I saw the deal post and checked the shipping cost too.
“필요 없는 물건이면 핫딜이어도 넘기려고 해.”
If I don't need the item, I try to pass even when the deal looks good.
