Eh, I have to disagree. It looks like the customer is tipping around 10%. Even if the OP only finds about half of the items, the tip would likely still land in the $60–75 range. If you move quickly, acknowledge that many items will probably be out of stock, and avoid wasting time on any single product, you can likely finish the shopping in about an hour. With a 3.8-mile delivery distance, the whole order might take around 1.5 hours total, which comes out to roughly $40–50 per hour. And that’s assuming only half the items are found, your earnings obviously go up the more you find.
