Gruntkowski and Martinez examined the impact of factors such as perceived risk and perceived usefulness on German consumers’ intention to purchase groceries online once the COVID-19 pandemic had subsided. They also compared consumer perceptions before and during the COVID-19 outbreak. This comment shows that Gruntkowski and Martinez’s research suffers from a number of problems, the most important of which is the use of an unrepresentative sample. They should therefore have refrained from generalizing their findings to the German population.

This comment points out that Lopes and Gomes, in their study on Portugal, erroneously conclude from their results that “being female negatively influences the online grocery shopping experience during the COVID-19 pandemic”. In fact, gender is insignificant.
