Brian, you can see the next week's ad on the Kroger website on Tuesday and sometimes I think Monday too. The totals for your sale won't be accurate when you make the order, but when you pick it up on Wednesday the prices will be corrected.
On any given day, if you look on my Kroger account, I have a cart of the things that I buy the most ready to go. If I'm shopping on a Wednesday which I almost never do, the cart will already be ready and I will submit the order early in the morning, on Wednesday. But before I pay for it and all that I clip all the current weeks coupons, the weekly digital deals, and whatever else is current for the current week. And then I will check my totals on my shopping cart and add or subtract as I need to, then submit my order.
I try not to shop on Wednesdays. It's too much extra work.
