Don't know when or if they're coming back but I ran into something really confusing with these. They're really designed as 2-person shops but they say they'll allow you to do it solo, which is what I want because I shop alone.
OK, so I took 2 of them for December. I'd already completed the first one and was doing the report when I noticed they'd added a note to the report that they would only reimburse for items on the menu. This was a problem because my standard main item, the personal-sized pizza, is off-menu. (It later occurred to me that I could just order the smallest pizza on the menu and get a take-home box, but that's beside the point.)
I figured I was stuck for the cost of the pizza, so I finished the report and canceled the second shop. I just got paid a few days ago for the shop I completed, and they reimbursed me for the off-menu personal pizza, despite the warning that they wouldn't. Now I don't know what the heck to think.
Sorry I couldn't answer your question but I just wanted to mention that.
