What I think is amazing is how so many people who "need" parts can't wait a few days for them. Pinball is a hobby for most people - unlike a car or your house heater there should be no reason not having parts for a week or two is any big deal. Or maybe "plan ahead" and stock some parts so you never have to have a "rush order"?
As stated earlier most pinball parts vendors work full time and do pinball stuff on the side - give the guys a chance! Especially someone like Ed at G.P.E. who has a great overall reputation. It is more important to "get it right" than get it quick!
