Price-volume table

[heikkilevanto]

Make a page with a table of the most common sizes and commonly used prices.

Hard code volumes to something like 10,20,25,30,40,50.

Take prices from recent beers, or hard code values. Or use some of the scrapers to get prices.

Might be worth making #140 first

I think it is good enough, I never use it anyway. Might even consider deleting it.
