I just bought some ice cream last night and ALL the packages that used to be 1/2 gallon are now 1.75 quarts. Same price, less product.
I usually buy the replacement policy on electronics. They pay for themselves in the long run. My husband bought me an iRiver MP3 player with a two year replacement policy for an extra $10. It started failing after a year or so, so I took it back. Because the technology had advanced, I was able to get a new player with a lot more memory and another 2 year replacement policy for the same price he paid for the first one.
We bought our daughter a Karaoke machine in 2004 for Christmas. We bought a 4 year repair/replace policy for an extra $30. It started showing signs of failure so I took it back. They don't carry them anymore so they gave me a store credit. I bought her a nice Sony stereo with the 2 year policy for an extra $10 over the original price. Best Buy for both the MP3 and the Karaoke machine.
The replacement policies have saved me hundreds of dollars and I have brand new upgraded products.
