ترجمة - انجليزي-ياباني - auction sale online sale

The second word "sale" is translated here as "raku-satsu," which is the way they say "SOLD! (to the man in the yellow shirt)" at auctions and things.
The general word "sale," meaning "a time of selling at discount prices" is
セール
which is just the Japanese pronunciation of our word "sale."
An older word, less commonly used now would be
特売
literally "special selling."
