Sorry, Swen. This one scrolled off my screen before I saw it. Just went looking and saw your question.
If there is an easy way, I don't know what it is. What I do is I make up a list of stuff that I buy anyway and search on those products every two/three days or so. When you get the results on a search, organize it by price and start scrolling. Be careful, though. You'll find lots of stuff like "Chef Boyardee at 25 cents a can" etc and then find out the shipping on a case is $30. Stick to the subscribe and save listings and the free Amazon shipping stuff first off. There's lots to go through.
On the subscribe and save stuff, it's free shipping no matter how big or small the order is. You can get $4 cases of 24 ramen for example shipped free to your door. It comes out to exactly what you'd pay locally but you get far more flavors to choose from and free delivery. If you want, only make the one order for free shipping and then cancel the subscribe and save two mins later. Don't tell anyone I said that. My last delivery this past week was two 50lb bags of hard wheat free delivered for $25 per bag. I can't beat that even shopping locally. That deal's gone for now but it'll be back in a week or two. Most deals usually are.
I got turned onto subscribe and save by some decent fellow here on the forum. My first order was two 72 boxes of Jewish Shabbat candles (standard 5" utility candles) for $6 each. I got two orders of those, four boxes total, and the deal went off the S&S list. Those were $24 a box last I looked. As I said, Chef Boyardee cans go on sale pretty often. If it's an S&S they can be 75 cents a can with free delivery....but even if it's not S&S, you can often find the same product on the Amazon free delivery if you buy $25 worth. You can get cases of 24 at 40-50 cents a can sometimes. Both the S&S and the Amazon free shipping deals are *really worth it!*
Apollogies for the typos. Tried to fix them as they popped up but missed a few, I think. Think I have a virus or something running the background here. My keyboard isn't working for crap tonight. Think I need to do a restoreto a few days back.
God bless.
