Because I've bought tickets to Mariners' games in the past, Ticketmaster sends me Mariners Mail.  Usually, this isn't terribly interesting.

But today's is offering discounts to next week's series with the Athletics in town.  The marketing line is:

Mariners Mail EXCLUSIVE
Ticket Discount vs. A.L. West Rival A's
As a Mariners Mail member, you can get a look at Jason Kendall and the Oakland A's new lineup with discounted tickets for the first two games of the Mariners next homestand!

And the prices:
(Location/Normal/Discount)
View Reserved    $10    $7
Field    $24    $11
Terrace Club Outfield    $29    $14

I think you can go to the ticketmaster.com site and use these directions:

1) Click the "T" link on either the 4/20 or 4/21 game vs. Oakland above.
2) Select the total number of tickets you want in the MARINERS DISCOUNT section.
3) Fill in the password -- "RIVAL" -- in the MARINERS DISCOUNT section.
4) Select either "FIELD SEATING," "VIEW SEATING," OR "TERRACE CLUB OF SEATING."
5) Click "LOOK FOR TICKETS."

If that doesn't work, send me a note (kirbyk at idiom.com) and I'll forward you the whole thing.

I dunno if I'm going to be able to go, but I figured there might be someone up here interested.
