I was fortunate to find the right tools and have a lot of website background knowledge to rapidly start my online store.
There were some gremlins that threatened to derail all my efforts. Like deciding on the right currency, I had tested by changing my shop default currency a few times and apparently Shopify have software checks and balances in place and I screwed it all up.
Fortunately Shopify has an awesome support system and with a bit of digging - they managed to resolve it.
