I'm not off until nine or so (gig's 300 yards away!), so I'd just like to say this...
If it WEREN'T getting almost impossible to find a TOTL or even MOTL arranger anywhere near you, sure, I'd say this isn't an issue at all. But almost every last one of us has noticed over the last few years how many stores that USED to carry arrangers have stopped altogether.
And, I can't for the life of me think of anything other than internet sales (and using the store as a free demo showroom) as the cause...
Perhaps you could tell me of another reason?
