Is there any purpose for Euria in this game?

Other than being one of the most hated customer, what will happen if I accept her high prices? (other than losing a lot of money, of course.)

No, her purpose is to ruin your trading-combo.
It's basically just bad luck, when she enters your store.

If you are willing to spend enough pix, she will eventually start selling rare treasures that would normally have to be obtained in dungeons.

She is annoying before you finish the game, but once on Endless I don't mind wasting my money on her since I'm already filthy rich. However, I only buy from her on the following scenarios:

- She comes with some item useful for fusions, or any kind of cheap junk
- She appears on the middle of a shop round and I'm on a really good combo roll.

So...
- Selling store decorations? If I already got them, NO.
- First or last on the round? Offer 1 pix, then see her go away really pissed off

You can avoid her by keeping your store very plain. She "can" sell you stuff that is very rare, even in the highest level dungeons, but really she's just a c-c-combo breaker.

Another trick to avoid her is setting up vending machines. If she buys there, she won't bother you.

Nice tips, everyone.
Thanks!

Euria is a good source for some treasures.
Offer her 200% of base price and she'll usually accept it.

Early in the game she will break your combos by offering you common items you already have, but she can be a source of rare/unique items.
