Ted here from Shopify, thanks for reaching out to us!
Sure thing! So our Support will need to apply this change internally, as you've already made a sale. Before this can be changed, I'll need to let you know of a few things that might occur. I've separated this into 2 posts as my reply was over the character limit.
After you have read the below and if you would like for us to go ahead with the change, please reply back to the email I've sent you so I can verify your account and I'll take a closer look into this with you. If anyone else would like to change their currency, please contact our Support here directly for more info.
If there is anything else I can help you with, please let me know, I'm happy to help!
Thanks a mill,
That's perfect! If you can reply back to my email I've sent directly to you (just to verify the account), I'll get that sorted for you straight away. :-)
