Good F2P ITEMS TO FLIP/MERCH?

So hi guys, i know that there is no "good" item in f2p to merch/flip, but still i have to make a living so please suggest me good items to invest my money on so i can have good profit, i have 1 COS and 15m cash. Add me ingame and we can flip/merch together  (RSN: rohit901)

yew logs, adamant ore, runite ore (if you get a large cashpile), diamonds, death runes, gold ore, gold bars, cut diamonds, rune arrows, coal, rune armour, nature runes.

Nature Rune, Lobster, Swordfish, Steel Bar, Adamant Bar, Coal, Gold Ore, yew logs, Law runes, any gems.

Probably the best f2p items list I have ever found was written by Eridex/CookMePlox which has the limits and current ge prices linked, so you can easily see if the item is in your price range. Scroll down past the p2p items as the f2p list is at the bottom of the page. http://runescape.wikia.com/wiki/User:Cook_Me_Plox/Merchanting_guide/List
