subtotal=Milk_chocolate_total+Dark_european_chocolate_total+White_chocolate_total+European_truffles_total; you may want to give them all an initial value of 0 otherwise you could be adding undefined values to the subtotal.

That might be because you did not initialize the variables to a specific number say zero, so the PC assigned any random number to those vars, and so this result.

No not a constant, but like this:
1
2
 
double Milk_chocolate_total=0, Dark_european_chocolate_total=0, White_chocolate_total=0, European_truffles_total=0;
double subtotal=0, discount_amount=0, discount_total=0, discount_percent=0, total,shipping=0, grand_total=0;

well you still have some undefined variables:

	if (Milk_chocolate>0)
	{
		Milk_chocolate_total=Milk_chocolate*Milk_chocolate_price;
		cout<<"\n"<<Milk_chocolate<<" pounds of Milk Chocolate @ $8.50\t $"<<Milk_chocolate_total;
	}
	if (Dark_european_chocolate>0)
	{
		Dark_european_chocolate_total=Dark_european_chocolate*Dark_european_chocolate_price;
		cout<<"\n"<<Dark_european_chocolate<<" pounds of Dark European Chocolate @ $9.75\t $"<<Dark_european_chocolate_total;
	}
	if (White_chocolate>0)
	{
		White_chocolate_total=White_chocolate*White_chocolate_price;
		cout<<"\n"<<White_chocolate<<" pounds of White Chocolate @ $10.50\t $"<<White_chocolate_total;
	}
	if (European_truffles>0)
	{
		European_truffles_total=European_truffles*European_truffles_price;
		cout<<"\n"<<European_truffles<<" pounds of European Truffles @ $12.50\t $"<<European_truffles_total;
	}


Most of those will be undefined when you check the if statement.

double Milk_chocolate, Dark_european_chocolate, White_chocolate, European_truffles;

should be double Milk_chocolate=0.0, Dark_european_chocolate=0.0, White_chocolate=0.0, European_truffles=0.0;
