I show only one shipping option & it ain't cheap!

I have both Fed Ex and USPS as options. When items are in shopping cart, the customer can view the calculator for both options, when checking out they are only given usps as an option and not all of the options show...only 3 of the 5... Here is when it gets worse...lets say you choose parcel; you go to check out and the cart puts express mail which is the most expensive. I am not given the option to change my shipping.....only to update my shipping address.

I finally have hits on my site and people creating accounts....now no one is buying anything and I finally know why....it has to be the shipping situation..it makes me look likke I am scamming...

Can someone please help me. Can someone see what I am doing wrong? Does anyone have a business that are experts in zen cart and can send me a link to their site?

The site is https://www.personalized2perfection.net put anything in your cart and see that when checking out no matter what you choose, it will put express mail in with no option to change...I am losing potential customers...please help before I lose any more.:frusty:
