Christmas crackers in the US?

Has anyone ordered Christmas crackers to be delivered in the US?  I've found a couple of places online but I wondered if anyone had any special favorites or recommendations.

This is one place I saw:

Or can I mail them myself?  I wasn't really clear on whether they would count as explosives or not.  I know it's ok on the Royal Mail side, provided they are in their original package, but I'm not so sure about the US.  I must be blind but the USPS page doesn't seem to say anything about things that cannot be carried in the mail.

Not sure if this helps but I found http://www.usps.com/aviationsecurity/

Doesn't Cost Plus World Market sell them in the US? Or do you want them from the UK?

I used to get them at Williams-Sonoma, and I've also heard people say they've found them at WalMart or Costco. There's also this place for ordering online.

Oh, maybe I'll have someone go look at Cost Plus etc. for me.  I just thought it might be nice to send some to my family in the US as part of their Christmas present.  The last time I was in the US for the holidays (wow, 6 years ago!) I did not see crackers anywhere.

When I lived in California, I always found them at Cost Plus. 

Agreed & testifying - I bought some at Cost Plus last year and have seen them at Williams-Sonoma over the last years.

I'm going to order some from Amazon.

It's my bf's first Christmas out of England, I want him to have something familiar. 

They also sell them at Target. At least they did 3 years ago....
