please can someone tell me how to find the shop

it's linked in the news post (link to the post on the right hand side of the news page)

here's the direct link tho: free shop

You can also find in the Commerce tab. It's in the last category, "Subeta".

I always have the shop list widget up and when specialty shops (Frey, free, snowballs, etc.) open up they automatically get added to the list.
