Shoddy Merchandise

Why is it every time I buy some kind of electronic device, it always ends up being "shoddy" and I have to return it to the store to exchange it?
A month ago, we purchased a new cordless telephone for the computer room. It had an answering system and two handsets, one remote and one base. It was working fine until today when my brother called and left a voicemail but the volume keep cutting out on it. I kept messing around with it trying to get the volume to stay on but it just wouldn't.
We took the phone back to Best Buy where we purchased it 28 days ago. Luckily it crapped out within the 30 day return time. I told them what it was doing so they said I could either replace it with the same model or pick out a different model. Well I went for the different model because once burned.....
Took me over an hour to get the new one all set up with our family members phone numbers, set up the answering system, etc.
