attention. the biggest walmart. put a $4 billion bid for a retailer called mass mart. it's just an offer but we also have a couple of deals that have been agreed to. the biggest, unilever is buying alberto culver, the hair products, for $3.7 billion. and finally, southwest airlines is buying air tran for almost $1.5 billion. and for wall street this shows that companies are willing to spend some of the cash they have been hoarding and take some risks and grow their company at this point. >> and so what does the southwest air tran deal mean for all of us the flyers. >> is it going to impact what we pay? >> it could. but at this point nothing is going to happen until the deal closes next year. but generally speaking, airline mergers mean less competition which could lead to higher prices but we'll have to wait and see because there's talk that the opposite could happen,
