[Q]: I used to give this product a good rating since it did the job well. It was then discontinued, so my husband and I have become &#34;users,&#34; meaning we tried them out for about 1 month. Now they are all gone or really expensive, and we've found nothing that's as effective. My husband has tried other brands in his quest to find something even remotely comparable that actually works but none of theirs do. They're expensive too.
[A]: Bad review


[Q]: My dog loves these so I buy them in bulk for her. But it is a rip-off to pay $6.45 at the pet store and $4.88 here. Not cool because it's cheaper on Amazon. Buy elsewhere if you can't find these... then you will have paid too much! It is almost as silly paying Amazon more than double price...when I can get 6 or 8 of her faves from the store. So disappointed. Will not order again. And don't forget...
[A]: Bad review


[Q]: The book was informative and very easy reading as all the other books written by this author. If you are considering starting your own business, go ahead with these books,or any of his others they will give good information. Mark
