£8m seems a lot.
But then for the price to be anything like what you'd feel comfortable paying, the player has to force his way out. From what we've heard from the club, Snodgrass is happy to spend another year at Norwich to get us promoted (which presumably means he'd also be happy to leave, but isn't going to force it). On that basis, he's always going to cost over the odds. Currently, you're in the fairly unpleasant position of the seller not needing to sell and the buyer having other competitors. Price is always going to be exceptionally high in those circumstances.
Also worth bearing in mind that Snodgrass will probably be the best player in the Championship next season, if he stays. That means he may well be worth, to us, the gazillions we would get from being promoted...
As I posted two days ago, his pace is the only real hold back to him. So while £8-10m would be an exceptionally good deal for us, I also have no doubt that it would be worth it for you. He is incredibly effective and if you look through the Prem, he's actually pretty unique for his style. The one thing he will guarantee, that some flair Jose Nirvana Acratopuliquez from the continent won't, is that he is a safe bet in terms of slotting into the team. You could almost certainly get a better player for the same price on the continent, but I'd say they'd need minimum 6 months to get used to the Prem and often they won't settle. The biggest teams can afford to buy and hold while foreigners aclimatise. Snodgrass will hit the ground running.
