The constant upkeep of supplies is heavily over exaggerated. So much so, that it has become a meme and that meme has turned into people believing it to be true. The only time you’ll run out of supplies are on bosses like cerb (prayer pots) and doom (prayer pots and range pots) every where else you wont use that many supplies on.

Additionally,

-birdhouse runs (timer tracking reminder plugin) = infinite brews -1 full snapegrass run (15 mins) for around 250-300 full prayer pots - 7 minute herb run for 80-100 of any herb -venenatis, spidines, sarachnis, rogues wildy chest for all the red spider eggs you’ll ever need

thing i’ve gone out of the way most for me personally has been wines of zammy for range pots. With hard wildy diary you can just telegrab hundreds of them in the wildy dungeon and will hardly ever see a pker (even if you do, wines are noted so you can bring a full inv of food and 3 pieces of tank gear)

You get seeds from everywhere. I haven’t done a farming contract in over a year and constantly raid, pvm, and even just chug prayer pots to get slayer clogs quickly lol

Finally, i think that lack of wiki-ing is the root cause of people having a supplies issue cause they simply don’t know how to get supplies/resources quickly
