Depends on the part; best you can do is go check. RS definitely has limited selection these days, ain't what they used to be. I'd say 50/50 chance, and I would go check myself. I'd say less than 50/50 chance the employee on the phone would know exactly where to look for what you need (unless you're shopping for a pre-paid cell phone).
