The $9 chicken place (which doesn't quite cover the cheapest option) starts at $0 shop fee here. It goes up to $3 and then $5. I did several (basically just for an almost free meal) because they're decent, fast, and very conveniently located. But I quit doing them unless they're $5. Got a call from a scheduler inviting me to do one for $10 and took him up on it.
The $15 chicken place popped up a month or two ago with $0 shop fee. I'd never tried it before, so I took it. LOVED it. Incredible flavor, especially the slaw that they use on their slider. Another popped up recently for $10 shop fee and I jumped on it.
