The Jason Bourne Collection on DVD?

Hi,

 I'm looing to purchase the Jason Bourne Collection on DVD (standard versions, not HD). I saw on your website that you said this costs about $35. I haven't been able to find it for this price. It seems that not too many stores have it and that when I've searched hard for it, I've found it for $60.

 Is there a shortage of this box set?

Thanks.

 Stephan
