Quite a lot of 'old' Legendary items price simply deviate out of its market value ridiculously, especially after lots of new Legendary items are designed into the market.
Such as this one:
Item Name : Anaquani Golden Idol

Name
Anaquani Golden Idol
Cost
1,400 credits
Stock
Unlimited
Equip Strength +2

Equip Defense +2

Only 'idiots' would pay 1,400 credits for a Legendary Item for STR/DEF +2.

I suggest to scrutinize every one of them and re-price them carefully.
This would make this game look more "well formed".
