The app is easy to use but the shoppers are all over the place and the system itself is sorry. I placed an order around 930 or so and after waiting for maybe 2 hours it updated and said it would be here around 1230. I checked all of the items I wanted to either refund switch or keep the same. The shopper said she was in line and my number wasn't able to be found (its always interesting system) and none of my items came. She refunded it but it wasn't. CS did it instead. Not satisfied at all.
