Q: Arm & Hammer's baking soda is aluminum free, they just don't write it on their packaging.  I wasn't sure so I called them and they said there is no aluminum in it, and they would have to state it if there was because people take the product internally.  This leads me to believe that there just isn't aluminum in baking soda.  And researching it showed me that there might have been in the past, but not anymore and not for a long time.  I resent that Bob's Red Mill writes "Aluminum Free" on their package and then charges a premium for their product.  It's also arsenic free, I hope.  If they label it "Arsenic Free" will we assume other brands aren't?  I don't like that kind of marketing.

A: Negative

Q: You can find this 6-pack for $40 dollars less at diapers.com.  No reason they should be charging this much.

Q: I was so excited thinking they had my favorite discontinued Kettle flavor, but was disappointed when I opened the box and found this substitution. I am keeping them but would not have ordered 15 bags of this flavor. It is a very good bbq chip but I could get this flavor at the grocery store. Why oh why do my favorite food items always get discontinued??? The one star is for the substitution. The country bbq is a 4 start chip, but not the chip I longed for.

A:
Negative
