Cheapest whiskey for green tea shots?

I’m supposed to supply green tea shots for a party this Saturday and I’m a broke college student and don’t want to pay 30+ dollars for one bottle of whiskey. Jameson is the one every website is saying, is there a cheap version that works? Idk what whiskey would taste similar. It doesn’t need to be 40%, I’m combining it with a 15% peach schnapps and the party is going to have other alcohol so I’m not concerned with the alcohol content.
