I don't know for sure but it may be regional. In my area, they always have a $5 off $20 deal that makes things slightly more palatable but even still, it's just bringing the prices back to what they really should be as others have said. I've uninstalled the app and completely stop going there entirely, the quality (not that it was ever great to be clear) is pretty terrible and there are so many better local places with way better value.

If you are in the 'couple of times a year' consumer type bucket you might not be valuable enough to do the deep discounting to. They offer the better deals to the 'couple of times a month' or more frequent users to keep them hooked.
