I just discovered 'bricks and pieces' last week. It's really strange the way it's a little hidden but much more stuff than pick a brick. This thread was really helpful as well as the excellent Jonas spreadsheet.
But what with the cart timing out and search being a little difficult I just ended up downloading all the bricks I could find (11K) and organizing them myself into web pages. I then added the ability to click on bricks to remember what I wanted.
In case it helps any of you (as this thread was so helpful), you can find the bricks I organized here https://nostalgic-wilson-b2026b.netlify.com/
The prices/what's available are a snapshot for Ireland/euro over the weekend.
I would be interested to know of any bricks I missed. I might deploy the page to a proper home/domain but knowing me I'll never get around to it. But let me know if it's useful for anyone and I'll be more inclined.
