New York City Saks earlier this week experimented with offering online "private event" sales of discounted designer goods, according to the Wall Street Journal.
Saks launched a 36-hour sale on Tuesday open only to those who received e-mails from Saks directing them to the site. The limited-time sale will be followed by another test in November, the report said.
The move comes as "flash" Web-discount sites pick up popularity in the United States.
To emphasize the short-term nature of each sale, Saks’ site features a large clock that counts down the hours, minutes and seconds, for placing orders. Quantities were limited, the report said.
