I wonder if this applies to the problem I've had ever since I've gotten a MBP in the fall. I am now on my 4th charger. No matter how I handle the adapter, it still manages to stop working within 3-4 months. The first one was probably my fault as I didn't keep the brick as ventilated as I could've, so I think it eventually fried itself.
The second one is still a mystery as I tried to use it one day and it didn't work. No LED, no charge. The third one had a slow death where it would take more and more jiggling and manipulating the cord to get it to work.
I don't get it. I wrap the cord around the little hinge things they have, keep them ventilated, and they still crap out on me. By far my biggest gripe with this MBP. If anybody else found a reliable way to stop this from happening, please let me know.
To provide a counterpoint, I've had my MacbookPro for over 3 years now and still have the same power cable and adapter as when I bought it. I never wrap it, toss it around in my bag with all my other junk, carry it in all weather, and I use it every day. My connection works fine and my brick hasn't overheated.
Not to say you're not having those issues, just that there are good experiences and bad experiences with every product.
I have been through 6 in three years, and the protip is to not use the hinges when transporting the adaptor. just loop it up in a large loop so that there is no strain in the cord
my last cord has now lasted 9+ months since I started doing this (I move it daily)
Are you getting them all replaced at the same store? My only thought is that it would be a bad batch (given I haven't heard of this kind of chronic issue elsewhere).
