Went to Roger Dunn yesterday to pick up a few dozen Taylor Made Pentas; dude at the counter told me the 3-for-2 promotion ended 1 Jan. So I got home, checked out TGW, and sure enough they still had them on promotion--so I bought 6 dozen.
I guess the promotion might be ending soon, or maybe they'll just suspend it for the release of the new Penta.
I know TM is releasing the new Penta soon, so the current version will likely to discounted again at some point until they're completely sold out. However, if you're like me and think the current Penta is the best ball you've ever played, then you might want to stock up now.
