Temporary loading problems with our website - 19 Oct 2007

Hi everyone,

As you might have noticed, parts of our site have gone a little haywire since yesterday. We were hoping for a quick solution but it looks to be a bit more involved. Right now the main problem is that our navigational links are not consistently pulling the right products.

Please be patient with us and we do apologize for the inconvenience. We're working with the administrators of the faulty server.

Thanks!!

UPDATE: With the exception of a few stray search problems, the site should load normally for you now and the checkout process should be smooth. If you are having any difficulties please let us know right away at tshirts_at_yellowibis.com and we'll sort it out for you right away. Thanks for your patience!
