shipping options

Hi,

I would like the customers to have the options to choose usps first class shipping or flat rate shipping.

I have been searching for a step by step from start to finish, finding bits and pieces here and there, so I have some idea of the steps needed, but still not sure how to go about this.

I currently use the flat rate option applied through the wizard and do not want to redo the cart pages again if at all possible and without connecting through the usps api - so ecart would figure amounts based on the weight column of the products table in the database and the ecart object shipping tab settings.

I'd like to add a drop down list on the cart page with the correct option amount changing to the amount whether it be first class or flat rate. The selected option would then show on the confirm page.

I hope this makes sense. Your help is greatly appreciated!

Thank you!
