Gift Shop merchant Amazon.com is offering a free ticket to see Star Trek when you purchase a DVD or Blu-ray disc from the selection of 17 movies between May 5, 2009 and June 15, 2009.

For more information, please see Amazon.com Movies & TV: Star Trek Movie Tickets Offer

Highlights from the list of movies included in the offer are:

• Tropic Thunder
• Cloverfield
• Face/Off
• Next
• and more...

When you buy one of the qualifying discs, you will receive a promotional code which you can redeem for a certificate valid to see Star Trek between May 8th and June 15th, 2009. The certificate is good for one admission, up to $7.50. That won't buy an entire ticket in most theaters these days, but it can take the sting out of some of the $10+ admission prices out there!

As with all offers and promotions, some limitations apply and it's good to read the fine print, so be sure to check out the terms, conditions, provisos, and other details.

Star Trek opens in theaters this Friday, with shows starting on Thursday night as well.
