This coming Wednesday tickets go on sale for 2 home exhibition games. On August 11th the Lions battle Denver, and then on August 31st, in the last game of the preseason, the Buffalo Bills come to town. The price of the tickets range from $40-$62, with some $70 seats still available.
The deal part of this is that if you buy tickets right when they go on sale Wednesday, you can buy the same number of tickets to a regular season game before they officially go on sale. To receive the offer you must buy through Ticketmaster.
