When we started this store, we didn't make an active decision on currency so the main currency for the store remained Swedish Krona (SEK). Man, was that a mistake. As the order started coming in it was harder to change it, but now it is done.
The currency mixup has resulted in lots of dropouts during checkout as Shopify only lets you check out in the store's main currency. Who wouldn't drop out if the currency all of a sudden changed?
Now, this is sorted out and we can go back to business as usual.
Sorry for the inconvenience.
