Yahoo stores only work with the UPS module

a client of mine wants fedex to work in his yahoo store

it would require some RTML coding I belive

Can anyone advise how this can be done?


Thank you in advance

Since this is at the top of Google still...

The best way I've found to utilize other shippers is to pack up and move the site to a different provider. Magento, OScommerce, or Volusion are all pretty good from what I've seen. Yahoo is a waste of money.
