I was at the doctors office with my infant and trying to move around with two bags, an infant and a stroller. At the time I was holding my daughter because she was upset and holding the bags. I was wishing I had a place to put the bags other than in the car seat. I was wishing for a clip or a hook for the handle so it was easy to get to but not in the way. I have a basket under the stroller, but that is very small because of the car seat in the stroller and is not easy to get bags in and out of. So I went to a nearby sporting goods store looking for a D-clip, but they did not have one big enough for the stroller handle. I then proceeded walking up and down the fishing aisles looking for something that would work. I ended up in the boating department were I found a big S-clip. It worked perfectly. Who would know that a boating clip would work perfectly for my bags to be clipped on to my stroller? Even though I used this on my stroller it would work for anything, such as a shopping cart.
