Is anyone else frustrated with poorly packaged food?

Here are a few examples: I bought a cup of yogurt that was spoiled due to an insufficient lid seal, a box of cereal with a flimsy internal bag that ended up with a huge rip in it after I tried to open it, a can of something or another that didn't have a tab attached to the seal (I had to use my fingers to open it, and they went right into the food as I was struggling to open it), and crispy things that were sealed in a bag that ripped halfway open with one pull of the seal.

I like to save money, thus I understand the economy of efficient packaging, but I think this is going too far.

Please, share your experiences. Also, is there anything else to worry about out there or that can be done as far as preventative measures go?
