To gauge the performance of your business this year, I suggest you not compare with 2020. Instead, compare with 2019.
2020 was an odd year for sure. While many newsagents experienced strong revenue growth in 2020, it was an odd year, one not to compare this year with in terms of assessing where your business is at today.
Having looked at data for a bunch of stores already, I think comparing 2021 with 2019 is a reasonable step. It will provide a better and more useful comparative perspective than comparing 20201 with 2020 in many situations. While the 2020 comparison is not bad, using 2019 as the comparison base provides more useful insight.
