Show HN: What Could It Cost?

What Could It Cost? challenges you to see if you really know how much you're spending on your groceries.

It's a simply daily-puzzle-style game that gives you 5 products from trolley.co.uk's Grocery Price Index, and asks you to guess how much they cost. The closer you are to the actual price, the more points you get. The price is averaged across a number of UK supermarkets, with the prices from October 2024. So if you normally buy something for £1.99, it might show as an unexpected £1.87 as it's averaged with another cheaper supermarket.

I often find myself not really noticing how much I spend on my individual items when shopping (I must be far too middle class), so thought I'd test out my knowledge, in a similar sort of way to the Name Your Price gameshow.

The site is open-source, you can find the GitHub link on the homepage. I made this so that I could learn more about Elixir & Phoenix LiveView, so the code is by no means clean at all :). I hope to clean it up as I learn more about Elixir.
