Can you edit items during checkout?

In a similar vein as having navigation or not, editing cart items triggers the “once they are in the checkout process, keep them there” debate. In the real world, we can modify the contents of our cart at any time we feel necessary – even halfway through the checkout process. We decide the extra batteries are not necessary and the clerk puts them to the side and we complete the checkout. Online however is often much different. Many stores force shoppers to abandon the checkout to remove or modify their cart contents. Yes, this may reduce the customer experience, but retailers may feel the payoff of higher conversions makes up for it. However, there is no evidence in our research that suggests either method is more or less effective as conversion rates were only a touch higher on sites who allowed cart editing during the checkout process. The single anomaly is retailers selling low ticket price items and allow cart editing have a growth rate over 2x those who do allow cart editing.

72% of Top 100 retailers do not let shoppers edit the contents of their cart once they have entered the checkout process.
