I want to say thanks to Joseph and everyone who's helped create this list.
In preparation for purchasing said supplies I put the list into a Google spreadsheet. I added columns for received, ordered, cost and location.
The columns are filterable so you can weed out the items you've purchased or, if you're going to a store for a few items you can filter down to just those items. (You'll need Google Sheets installed on your phone for mobile use)
If anyone is interested this sheet can be found here. It's read only so you'll have to go to File-->Make a Copy to copy it to your google account.
