Q: An airline company I've been keeping track of recently held a sale. Before the sale, the airfare prices were very cheap on weekends, and very expensive on weekdays (Sat, Sun, long haul flights are at $700 -- Mon-Fri are at $1,300!). During this long sale, their cost is $900 to $1,000. Maybe, because the cheapest flights have been booked at the sale's commencement and all that's left are the not-so-cheap but not-so-expensive fares...

Should I buy now or wait a few days after the sale?

A:
Buy airfares now or after the sale?
