Hey there @creedon - thanks. I actually found the code I used to hide price, and quantity posted in response to somebody's question last year. The code works for hiding price, seems to work for hiding quantity too. But, what I can't figure is how to hide the add to cart button.
To be brutally honest, I don't really need a store/shop/commerce function. I'd much rather have a gallery block, and thumbs, and copy on the right I can control on their 'fluid page design'. But I can't find that as a template anywhere. A commerce template is the only template I can find on squarespace that offers the gallery+thumbs on the left, and the space for title and body copy on the right. Having breadcrumbs is a bonus.
So, I either try my darned hardest to figure out how to hide that button. Or somebody needs to prove me wrong/show me where in SqSpace templateland this gallery and description style might exist. (see screenshot below for my ideal layout. )
Anyway, thanks for responding, and I am glad I found your code on the forum to hide price. I'm part way there.
