Great and almost completely painless to use. My one gripe is that they offer great cash-back, but only if I start with an empty cart and complete the transaction in one session. That's not how I shop in many cases. For things for my home or spouse, I put it in the cart, then review later with my spouse. For groceries, I put everything I _think_ I need in the cart, but I can modify my order until the afternoon before delivery - and I often go back and add one thing I forgot - like milk. This isn't "gaming the system" at all, but I don't get cash back. Is there some way to have the system let me still get cash back in these cases?
