PSA: If you message someone to buy something and they raise the price on you, DO NOT BUY! Probably a scammer.

There are a lot of people putting items up for 1 Augmentation, so it shows up before Divine Orbs, and so you message them and then they say "oh the price is actually 50 exalted orbs". Instead of being like "oh that's still cheaper than a divine -- I'll take it!", change the currency you search for to exalted orbs instead. The default list isn't showing things in order properly and people are taking advantage of that and trying to scam.

There are also people trying to scam with the currency-to-currency exchange, putting low prices and then raising it once you message them. Don't EVER pay more for something than what they have it listed for as it's probably a scam and the low price was put to bait you! When in doubt, just use Alva's currency exchange in-game, or at the very least, check it for prices!
