add flat fee to every purchase

[Guest ckwall]

I am looking for a way to add a flat fee of $3 to every checkout total. The product I am selling needs to have a $3 charge in addition to everything in the basket. Is there a way to do that?

Sure. In fact, one of my clients has a month-long bottom-line % discount. Instead of a proper mod, I just rigged the basket total calculation.

In the file: /includes/content/cart.inc.php, there are several places to change. And in cart.tpl, there needs to be a line that explains the charge.

Look for this in cart.inc.php:

$view_cart->assign("LANG_CART_TOTAL",$lang['front']['cart']['cart_total']);

$view_cart->assign("VAL_CART_TOTAL",priceFormat($grandTotal));

Just above that is the line that sums the various charges (tax, shipping, etc). Just add 3.00 to that equation right there.

Dont forget the print order form needs to reflect this aswell !!

Could you add it into the shipping fee? You could then rename 'Shipping' to 'Shipping + Handling' (or whatever the extra fee is for).

Great tip, I've used on my site -- but also discovered that you have to add the amount to the PayPal module -- by adding a line to transfer.inc.php:

<input type='hidden' name='handling' value='2' /> (or whatever the value you added on the cart page)

This is because the PayPal script takes the individual values for subtotal, tax, and shipping and adds them again.

If you do not add the handling item it will not be included in the PayPal charge.
