Weekly Product Action Page

[HansjeW]

Hi Guys, 

I want to do a weekly special action, where I bundle a couple of my products in a box. After this week this special action will be over. 
Now my question is, should I create a new productpage for this every week or should I just use the same page with a general URL and just change the content every week?
What would be the best choise SEO wise?

Thanks! 

Hannes
