they will cut your arrows for you if you specify the length for 2 bucks a dozen if i remember right...just make sure you askif the arrows come with the inserts...i bought a dozen arrows one time and they didnt come with inserts.
also they have the best prices for feathers....brand AAA diecut...cheap and justas good as truflight.
