If you're stuck for a particular value - as often happens for meter shunt resistors - apart from winding your own from resistance wire (assuming that it won't matter if the resistor is inductive), it's always worth considering using a couple of resistors in parallel from the more common E12 range. EG: 6.2R + 3.9R = 2.394R (99.75%). 6.8R + 3.9R = 2.478R (103.25%)
Lots of parallel resistance calculators on t'internet to take the pain out of doing the calculations! EG: http://www.1728.org/resistrs.htm
