For now, I don't have the code for you that offers that functionality.

On a related not however, we've actually been wanting to move the shipping charges box from the product details page to the shopping cart contents page. 

We'll talk with our developers about how that can be done, and hopefully be able to offer it in a couple of months.

I understand your desire perfectly.  It just doesn't work that way yet.

Market Theme is an evolution in process.  It started out very humbly, and has grown and improved in features over time.  The reason it's like this, is because it started out as simply a way to connect a single product to Paypal checkout.  A shopping cart system was added later, then options, then variable options pricing, etc.

For the meantime, I think I may be able to offer you some workaround code that could do as you desire.

It will still ask the buyer to select a shipping choice on each product page, but it will only calculate one single charge.  (not multiples)

One drawback though I want to tell you, is that this code change will only take the shipping rate of the first product, and ignore all the others.  So, if a person chooses the first product with a shipping rate of 3.95, and then chooses another product and selects 6.95 shipping rate — this code mod is only going to register 3.95.

Now, in all practicality your buyers are going to choose the same shipping level for all items in their order, so it probably won't be a real issue.  (Certainly not a major one.)

But, it should get you up and running in a manner that is acceptable to you.

Here's the code mod for Market version 4.1:

1. Open the file "ajCart/cart.php" for editing.

2. On or around line #98 locate the line:

$Shipping += $crtShipping2[$item] * ($crtQuantity[$item] - 1 );

and change it to this:

//$Shipping += $crtShipping2[$item] * ($crtQuantity[$item] - 1 );

3. On or around line #100 locate the line:

$checkout .='<input type="hidden" name="shipping_'.$i.'" value="'.$Shipping.'" />';

and change it to this:

//$checkout .='<input type="hidden" name="shipping_'.$i.'" value="'.$Shipping.'" />';

4. On or around line # 103, locate the line:

$ShippingTotal = $ShippingTotal + $Shipping;

and change it to this:

//$ShippingTotal = $ShippingTotal + $Shipping;
if ($i==1){
     $checkout .='<input type="hidden" name="shipping_'.$i.'" value="'.$Shipping.'" />';
     $ShippingTotal = $crtShipping[$item];
}

5. Save the file, and that should get you going.
