Stud broke

When i got my new tires put on, when i got home i noticed one of my studs broke partially , how easy is it to replace it? Would a tire place fix it, if i ordered the parts? Do i even need to order the parts or would a tire place have various studs?? any help would be appreciated since im in the dark on this issue, it is a stock 5x 4 bolt pattern so i dont know if that helps or makes a difference at all. Thank you
