Comment on Gruntkowski, L.M.; Martinez, L.F. Online Grocery Shopping in Germany: Assessing the Impact of COVID-19. J. Theor. Appl. Electron. Commer. Res. 2022, 17, 984–1002

Round 1

Reviewer 1 Report

Does the introduction provide sufficient background and include all relevant references?

It would have been useful to also provide some general standards by the key scholars on various methodological practices, rules, and ideals in quantitative research. This would add more value to novice researchers and greater theoretical support for the critiques leveraged on the work of Gruntkowski and Martinez [1].

English errors- Tenses, awkwardness, etc. e.g. lines 52, 61, 62, 113, 130 

Reviewer 2 Report

The authors critique Gruntkowski and Martinez's (2022) paper. After a careful examination, I agree with the authors.

Would also suggest incorporating the following points for a better readability:

1. Page 2, Line 61 (In particular the combination of perceived risk and perceived trust in one and the same model surprises.) Please illustrate the issue more clearly. Gruntkowski and Martinez (2022) has provided the reference for the constructs, where is the problem is not presented clearly. Is it the incorrect reference or incorrect adaptation of the construct?

2. Reliability was carried out using Cronbach's alpha, however, composite reliability, AVE, discriminat validity was not addressed. You may want to add problems related to convergent validity.

3. Refer Table 4; Few hypotheses have p-value more than 0.05 (risk, convenience and situational factors) and hence they can't be accepted. However, authors claim all hypotheses to be accepted. You may want to present/critique the same more clearly.

A second round of professional proofread will improve the manuscript.
