Misleading advertising & incorrect currency

Yes, there are a few free themes, but the majority of them are for sale - I would have clicked on a for sale set of themes if I wanted to buy. I’m temporarily in another country, so the pricing came up in that currency, not my own. It was a nice assumption, but not accurate and I don’t see where to change the currency. This reads the location rather than the settings in my Mac for my preferred currency.
