Compiled List of Tips & Tricks

At catherbby you can buy fish from a guy, if people sell to him. There are currently lots of people fishing there and selling their fish, so you can get them for just 1 gp.
Theese fish is raw, but there is a cookie place in the next house, so its also free cooking xp

not sure if its a great tip but using big net fishing at level 16 can sometimes get you caskets. Today i got 681 gold from one so this could be seen as a money making tip?? but im not sure how good it is.

In Ardounge you can steal silk (requires 20 thieving) and trade it to people who are purchasing it and make near 20k per hour selling to these runners. Alternatively if you don't want to get the 20 thieving needed, you can be one of the runners; you make quite a bit less, but don't have to do any stealing.

As some of you know I've been trying to get no.1 on the Highscores for herblore, falling short of 4th place by only a little bit, shortly after I fell down to 50th place due to inactivity, anyway, I'm writing this to let you guys know what to do/where to get resources/what to make, etc, Gonna keep it short and sweet.

NOTE: You're going to need about 150k for this to be possible, but you WILL make it back.

Levels 3-26: Attack potions
1. Go onto the a forum such as D2JSP, RS, etc, and buy 1k or more vials filled with water. (60kish)
2. Buy 500-1000 guam leaves, and mix the vials with the guam leaves. (Price unknown)
3. Buy 500-1000 eye of newts, either from taverly, or again, from other players, and mix them with the unfinished potions to make Attack potions. (1500-3000gp, from Taverly)

Levels 26-38: Energy Potions
1. Either sell the attack potions and buy more vials, or empty the potions to free up the vials. (N/A)
2. Buy 200-800 harralander, and mix them with the unfinished potions. (Price unknown)
3. Buy chocolate, best to buy it from other players in bulk, you will need about 200-800 corresponding with the amount of harralander you purchase. (Price unknown)

Levels 38+ (for now): Prayer Potions
NOTE: Not sure this is the best option still, as ranarrs are above 1.1k each... but this is how I did it.
1. Buy another 1k vials. (60kish)
2. Buy 1000 ranarr. (1.1M, I bought mine for above 70k >.<)
3. Buy 1000 snape grass for about 250ea, again, I bought them for much cheaper but prices went up.

The best place to buy from players is forums, or Varrock west bank, w2 or w1.

If you follow that method you will be around 50-60 Herblore, selling the prayer and energy potions WILL make you profit, but getting the resources to make the potions (especially prayer) is costly.

I'll update this as I go along, hope this helps some of you.

Hey Everybody!
(Just a quick little note, since everybody are basically "noobs", this guide is just for people to make some money, at low levels)

I'm guessing you're here because you want to make money so im going to get right to the cache.

First way:

Picking flax. I'm sure everybody knows this method. Flax at the moment is at about 30gp. And bowstrings are at about 35-45gp.
You have to run all the way to camelot, but this is a good 1k per minute.

Second method:

Cutting willows and maples. Right now a lot of people are fletching trying to get 99. And the best way to do that is by fletching maples. This can also relate with the first method. So if you can cut maples and get bowstring. Each willow is rougly 15-18gp per log. This is what I have been doing and I have made a decent amount of money.

Third method:

Killing cows for cowhides. I like this method because it made me some fast cash, and it gained me some skills. I sold all of my cowhides for roughly 20-40gp ea.
