Have you gone through TurboTax's filing process? It starts with ~$149 upgrade for me, I believe. They have countless add-ons that popup throughout the filing process beyond just that (annual audit defense membership, get your refund faster, etc). So many up-sells and cross-sells, it is pretty disgusting.
I stopped using them last year because it was just too much. I can easily see how someone could end up with a multi-hundred dollar bill from them. Many of the popups are tailored to look like you need to say yes.
So they're trying to completely fill the price shadow underneath the $500 or so a very basic "entry-level" accountant relationship would cost — and fill it with a zero-marginal-cost roster of non-product products and non-service services. Terrible.
