The answer, based on evidence, is no.
Through one of my shops we have offered boxed Christmas cards in-store and online all through the year. Online sales have ticked along while in-store has been slow. Then, in July, online sales increased further, and at the start of this month, sales spiked further again.
The online sales indicate that planners are thinking of and buying for Christmas from the start of July. We have seen enough early sales to encourage us to continue with the year-round approach, and to know some possible trends for this year.
I post the question Is it too early to put Christmas cards out in the newsagency? today because some newsagent colleagues tell me they will hold off putting out Christmas until the start of November. In my experience, that would cause the business to miss revenue there for the taking.
I used to only put anything Xmas out after the first of November but that changed when covid came along. Now I put it out as soon as I get it. I am surprised at how many early Xmas shoppers there are.
It’s NEVER too early.
I go out with christmas mid October. I am in a country town and any earlier invites complaints.
