As a general rule you should make money on shipping and handling or build it into your price. Most customers will understand they need to pay shipping costs.ShadowDragon said:
I go about it another way. I charge a fixed handling fee and then add a shipping cost based on the cost of the order. The larger the cost, the smaller the % of shipping charges. Something like $3 for the first $10, $4 for the next $20, 5$ for the next $50 and then $6 for everything over that. So the most we charge for shipping is $2.95 handling and packing + $6 shipping. Our price for our product has a nice profit built in that if shipping is more to us we are still covered.
Our shopping cart software calculates the shipping so the customer is never presented with a complicated formula. If someone calls us then we just quote a flat charge without telling them how we arrived at it.
