catablog tutorials

I was trying to set up shopping cart for my Catablog items, and did not know what to do and where to start..   I am still not getting the shipping right though I've added.   But the shipping comes out at multiples of $5.50.   but adding two different items gives $11.00 shipping..   Is there I can correct this so that each item has first item shipping charge and subsequent item shipping charge..   I also find that once item has been added to cart, decides to add nothing further to the cart, then they cannot return to the cart to check out.   I found this code on the paypal website for Go to Cart button and I added this to my page.   But just to the page of items to buy..   Sorry for all the I do not know what I'm doing and I feel I am so near, and yet far away from making this work..   I appreciate all of the hard work that went into your tutorials.   Read more
