Average price for what ?
1- This could be valuable when " AVG " itself already a product with an uncertain price than it help users to follow the current price of "AVG"
2- Another option if this name be used as a searching tool it may make sense, such as i want to buy XXX product and when i type this product on this platform it will give me the average price and other prices at different platforms and countries, with/without tax. But still better to use Average than AVG... unless end user make good afford with SEO to make the domain name popular until everyone accept the term AVG
Conclusion: If you wait for the end user it may take so much time for a price $$$ or $$$$. If you are willing to sell it on NP it may only get handreg value.
Good Luck!
