Of course you're alarmed at the percentage of shopping carts that get abandoned. And you'd like to reduce that number but first let's have a think about what's actually going on, then perhaps we'll have a better sense of the actual scope for improvement.
Your visitors are certainly interested in the product, but were they really on the verge of buying before they abandoned the shopping cart?
Naturally the visitor wants to know the price, the actual total cost to them of buying your product. And in all likelihood they are comparing this total cost to that of your competitors before making their decision to buy. But to get this information, to know the total cost involved, the final price inclusive of shipping costs, handling charges, sales tax and so on, the visitor almost always has to add the item to the shopping cart and fill in a few details.
So it should come as little surprise that shopping carts are being abandoned. Sometimes the total cost will be higher than the person expected, sometimes one or more of your competitors will turn out to be cheaper in this instance, for this person wanting a particular delivery method to their chosen destination.
Was there a problem with the shopping cart? - Not really.
There is often scope for reducing shopping cart abandonment. But the room for improvement is rarely on the scale that people imagine.
