I have been watching partyhats and the rare market closely ever since last year. Partyhats have been driven to a sky high because of the high demand and small amount. Oddly enough, Purple broke this chain a few days ago.


People say that one offer for max or lowest in ge can change the price of a rare because there are so few left in the game.
The fact that purples are dropping in price is unexplainable. The regular supply/demand law has been broken. People have come up with a few rumors/theories as to why this is happening.
-Jagex is manually changing the price to make people panic and make
partyhats crash.
-Some theory that people have max offers in ge has a effect? (takes a load of
money)
-A old ancient account was discovered with quite a few purples and they sold on ge.
If you are market savvy or know anything at all post it! Discuss and feel free to express your opinions.
