Hi!
I thought I’d share this idea for everyone, in case someone finds it as useful as I do 
I quite often order sewing supplies online, and as they sometimes have quite high postage / delivery fees, I try to order as much at the same time as possible. Of course this usually means that I end up ordering more than I need (oops).
I have now started to collect a shopping list in my notions, so that I can easily see what needs re-stacking or what I have planned to order next.
I just created this as a new notion type, and added the other notion types as subtypes (for easier classification once the items arrive). Then when I do get my order, I just change the notion type and subtype for the correct one.
This way I can filter by shop, have links to the actual products and keep track of what’s already (pre-)ordered.
