As Lefty say's, 'priceless', though one has to wonder why on Earth, or in your case 'a rogue planet called Nibiru' would you design a circuit with a precision op-amp costing $14 and buy for less than one dollar, 50 resistors that are a inferior 5% carbon film?
I can see that the two 10kΩ resistors probably do not need to be exactly 10kΩ, but for me, it's about good design practice.
Out of the 48 resistors left over, a time will come where you wished you had 1% metal.
