I don't think Instacart works with WinCo. At least they didn't a while back and it wasn't an option when I tried in their app.
I do not know but my guess is yes. I think they go where you want them to go. Also you can purchase online at https://www.wincofoods.com/shop/. Also you can get digital coupons for winco online on their website.
