With football season now here, and the Brewers finally mattering in September, the Wisconsin Better Business Bureau is warning ticket buyers to watch where they get their tickets from.

In Thursday night’s buyer beware; the B.B.B. says that the secondary-ticket market for sports and entertainment events is a $10 billion industry, with on-line sales making up about 1/3 of that.

The bureau recommends that buyers deal with internet sellers with a B.B.B on-line seal on the site. Also, if you buy tickets in an on-line auction, choose a seller with a long history of solid dealings. Pay with a credit card or other on-line payment that offers protection and potential reimbursement.
