The interesting thing his is the bag is BoE and that means one thing... Re-selling. Many people will not be aware of this new bag and there will be profit to be made. 3000 gold might seem a lot, but it really isn't to a lot of people (especially your target audience) and reselling this for 5000 isn't going to be impossible.
It's a risk, but I'm bringing it to your attention so you can decide whether you want to take it
