Pros
Prefered members are good b/c you can have repeat good customers and leave out the bad. Sounds too good to be true. And that's because it is. They ruin everything with their rating system.
Cons
The rating system on Shipt is absolute cancer. They take the last 50 deliveries and use that to base your ability to receive orders. So 50 5 star ratings is perfect. But if you ever, ever, ever, get 1 rating under 5 stars, expect your orders sent being sent to you to drop about %60 percent. If you ever, ever, ever, get another rating less than perfect 5 stars and you already ahve say 1 4 star rating. Expect your order to almost vanish. It's a desert wasteland. The only orders you will be getting now are the non tipper, low low tipper, and customers who love to rate less than 5 stars. 100% you are never going to return to a perfect score, because you need 50 orders to remove that 1 "bad" 4 star rating. Yes a 4 star is just as bad as a 1 star on Shipt. But remember what I said above, the only orders you are going to get are more bad customers. The orders that all the current perfect 50 5 star shoppers don't want, you get those. But even worse, if your avg is like a 4.94 vs say a 4.97, you won't even see the bad orders b/c orders wont even get sent to you b/c all the people above you are grabbing them. You literally are only going to get the no tip orders sent to you b/c all the people above you know who these customers are and they reject them further sending them down the line where you are.
