I tried one once at the old fee ($18) and decided that that fee was too low for the amount of work involved to try another one at that price. Plus, I did not like that the money was debited from my bank account right away, but the refund took 3-4 days to process, so I had to have a few hundred "extra" set aside in my account for the shop. I would do it again for a higher fee, but not at the fee they were offering.
Then, they lowered the fee to $14.50. I watched it sit awhile and noticed that they've now bonused it another $1.50... making the fee $2 lower than "too low." I'm glad to know that no one (at least in my area) bit at the $14 fee. Maybe it'll come back to something a little more reasonable for the dual interactions and days of "bank watching."
