Official Riot Merchandise at PAX East

Hey, I was wondering if Riot will have any of the items from their new online store for sale at PAX East. I know there will be no official Riot booth but I was wondering if they will still sell things through one of the merchants that will have a booth there.

If not, I'll just order through the website but it'd be cool to buy some things while I'm there on Saturday.

Thank you for any information. :)
