Fact: Notaries in different areas are paid much differently. If you're in a metro area, odds are there are many notaries competing for the, now declining, work available, so, yeah, the cheapest gets the business and then some desperate notary says OK to a ridiculously low offer...and a lower 'cheapest' is set. Which is a really good reason to just say "NO'.
Fact: In rural areas with a lower volume available and far fewer notaries, the pay is considerably higher. Like 2 1/2 times higher. Again, this knowledge that they most assuredly can and do pay more ought to make you realize that's another good reason to just say "NO".
Fact: As long as they can find anybody to accept these ever-decreasing fee offers, why would they offer more? This isn't rocket science and they're saving enough on too many jobs to be able to pay an experienced notary to correct any serious issue. Again, another good reason to just say "NO".
