Just as with payment methods, it is crucially important that your shipping methods are presented in a crystal clear way. A lot of stores will only offer their customers one shipping method and one choice during checkout, but even in that case ensure that it is clear what costs are included in the shipping charge. For instance, handling, service fees, administration costs, and so on. If you communicate clearly what is included in your shipping price, your customer will also understand better why your price is what it is. Especially, if your shipping prices are higher than your competitor's but you offer additional services, be sure to make your customers aware of that!

It is possible to have several shipping methods in Magento active at once. Take care to test your settings thoroughly, otherwise undesired scenarios can occur. For instance, if you've set a Flat Rate of 4 and the Free Shipping method as well, the shipping methods will be displayed like this:

It's clear what your customers will choose! Again, always test your checkout process extensively. If you offer multiple shipping methods, list out the differences between each one of them and also describe the advantages of the more expensive ones.
