Is this list stiill valid?

I keep getting told that the items list here are out of date and over priced as I am quoting these prices to ppl when buying and selling items.

The link is here: http://www.guildwarsguru.com/forum/s....php?t=3000000

If it is, outdated then which price guide should I use?

that thread is way out of date. The new one is located here: http://www.guildwarsguru.com/forum/s...ad.php?t=66631

Interesting; it lists the Flint's Fleshcleaver as 1k and hard to sell. I sold it for 10k easy a few days ago.

You were lucky. it is ~1k, and very hard to sell

That's the thing about selling stuff. It's only really worth what the person buying it is willing to pay. If someone started saying an item was worth a bunch of money, in a week or two it would start selling for that inflated price regularly.

Always shop around the various districts to see what the market price is at...
