I think you should be charging more, because your time spent answering convos. is time away from creating products....you need to be paid for that time.
-Keep a word file of answers to the most frequently asked questions.....so you can cut and paste these in response.
OR
-keep it short and sweet, tell the customers, the answers to their questions are on the Policies page, give them a link to that.
- have a few friends look over your listings and policies page and give feedback on what could be clearer, so that people will ask less questions. It may be possible to tweak your listings. Consider asking elderly relatives and those who have little understanding of graphic design so you can understand this type of customer's experience when they look at your shop.
For example I noticed this.
"● Not numbered or perforated, that can be added for an additional charge "
You should have a link to the listing for this charge, so that the customer can easily put it in their shopping basket. That way they don't have to search for it, or contact you to ask about it.
- Consider limiting choices. Too many choices equals confusion and therefore more questions. Consider streamlining the choices and even products. Keep the most popular/best selling, drop those that do not sell well.
- I agree that a certain # of changes are included, after that, additional fees apply.
