Cal here from Shopify, thanks for reaching out to us. I totally understand the need to temporarily step away from your store right now, with everything going on. As part of the response to Covid-19, anyone on a paid plan can pause their store for three months, and then return to it.
You can learn more here about the Pause plan here. You can reopen your store any time during the three months. If, after three months, you don't reopen your store, then you are upgraded to the Pause and Build plan, which is $9 USD per month.
Let me know your thoughts!
