We love these bags.  They are strong, easy to use, and priced right.  I was especially impressed that I ordered them from Amazon one day, they shipped the next, and they arrived the day after that.  We have bought these from Amazon on a regular basis for several years now and will continue to do so.  And I think the price has come down since we started ordering them.  I can't believe we got them so fast!  We have two dogs and the 200 count lasts about three to four months with picking up their poop every day.  My husband likes them better because they are thicker than most poop bags and don't tear, especially in the winter when the ground is frozen and harder to deal with.  We highly recommend them, especially for big dogs and in harsh winter climates, where you have to pick up after them.
