Hey there Nnenna!
Genevieve from Shopify here :)
That sounds like a really good idea!
There is an app, AnswersEasy Support, that allows you to set up a responsive FAQ to embed in your online store. You could set up your store navigation such that visitors to your store reach this page before they access your contact details :)

Linc Care also looks like it could be a good option for you:

Hope that helps!
