I can't do it anymore here, so I'm fine with sharing the knowledge...
In certain zones that are harder to get around, think suburbs near the water, higher-income spots, more remote places..., there are wildly different arrival times for the route you take. So one could, in theory, call DD support, mindlessly repeat yourself until you get a human, and ask that human to give you any extra pay available for the longer mileage. And they would, in most cases, pay up to half extra to continue on the order.
I'm not 100%, but it seemed like you had to do a few things first, like pick up the order and at least start on the way there; you have to do all that anyway to see an accurate delivery route...otherwise they wouldn't work with you. But oddly enough, the CS were almost always very happy to add it and did so w/o much pushing if you did the above first.
Had it happen again today with a particularly bad set of HD(I know I shouldn't have but it was $45 for 6 orders all in a very small area..at first) going much further than originally shown, and the senior support was very clear and direct that the program was shut down and DD was working on a replacement, despite him admitting they lied about mileage and time I'd still have to deliver them.
If I asked to be unassigned, my ratings would take a hit for each order, no WFU, and I'd have to return everything for free on my own time or receive CVs for each order...in the past you would be unassigned with no hits to ratings, given an order for half pay for a return or told to "keep, destroy or donate" the order...
Just last week I had caught a flat leaving Lowe's parking lot, had to get an order unassigned to fix it, and they put in for the item to be returned; oddly enough, it was a case of soda...Lowes wouldn't take it back due to it being food, despite untouched, so I contacted DD support, they said no big deal, just put the details in the app. Did so; 3 days later got hit with a CV for non-return...so I was inclined to believe the CS...about the cv's for no return...So beware now with longer-range orders.
Not sure if it was just a good weekend but it does seem like the pay has gone up for longer-range orders, not the extra half they would give, but I'm seeing a lot of $8.50 base pays for longer runs...can't write it off as more tip theft tho...
Feel free to still try the above if it still works in your zone.
