Lowest Price

Can people help me monitor prices on a few things? I'd like to buy some armour, but when it's at it's lowest price (crashes), and some other things.

I want an abyssal whip, dragon platelegs, helm of neitiznot, rune platebody, sharks, potions. Can people tell me when a certain item is as it's lowest? Thank you.

 

Here's a helpful link: http://services.runescape.com/m=itemdb_rs/frontpage.ws. Just type in the thing you want to search and look at the graph to see if it's at a low point

 

So in other words, a whip has already hit it's lowest point? Thanks a lot for that link. Buying a whip now. Will check the other items.
