I usually buy most of my groceries and baking supplies at Kroger, ince it is close and therefore, easy to get to; plus they have great sales. I like Dollar Tree really well also, and you can't beat most of their prices; but I don't have one close to me, and it is not worth the trip out there for just a few items. When something takes me close to the Dollar Tree, then I usually stop there.
I am also starting to buy more of my food items on Amazon. You not only can find great deals on there, but the shipping is free, and gets there in just 2 days; so unless it is something that I need right away, Amazon is wonderful.
I have the Prime membership, and that is worth the cost, if you order much from there at all.
