I have seen the My Buggy Buddy clip before in my pregnancy searches online and thought I would investigate this further.
Kiddicare but there are plenty of places you can buy the clip from, ours cost £4.50 but the RRP is £5.99. There is also a large version if your pram/buggy has larger handle with RRP £6.99. The lock version RRP is £8.99.
The clip is easy to put onto the handle of your pram/buggy and you can put it wherever you like, we ended up putting ours to the side slightly as we found bags got in the way of pushing if you put the clip in the middle of the handle as we still had our changing bag to consider.
We went for a trip to Cheshire Oaks - a great place to check out the clip. It was a very successful shopping trip and the clip did its job perfectly. It was easy to use and it allows you to move around the shop without bags and buggy in hand. Plus I had a c section and constant bending still isn't great for me, with the clip I didn't need to bend over.
Obviously you don't hang too many bags on the clip, you need to make sure the pram/buggy doesn't tip over. Also you always remove the bags before you remove your child from the pram/buggy.
I would definitely recommend the clip, I have found it really useful! I may consider buying another one for the other side of the pram in time.
