What level of politeness/respect should a customer use towards a shop owner?


I made a purchase at a store and received an email from the shop owner.

What level of respect/politeness should my reply be, in addition to using 丁寧形
throughout? For example, how should I choose between 〜てもらう and 〜ていただく? Should
I use 尊敬語 and 謙譲語? Should I address the store owner as Xさん or Xさま?




It depends on your style or relationship between the shop owner, but you are
not to be blamed as long as you use regular polite style.
