Hi there @K1wrt!
Don here from Shopify
I'd be only too happy to answer any questions about using Shopify you have here.
Not to worry, if you're still in your initial free trial period you will not be billed until your trial would have ended anyway so you don't miss out!
Do you have everything ready for your store launch so far, or are you still working towards setting a date?
Let me know here if you have any other queries we can help out with from here!
