I have been buying Zip loc containers now for many years and I don't know why I constantly by them as they only last me a good month if that. they are great for storing your dry foods, meats, veggies and other foods but as soon as I put them in the dishwasher they discolour right away. My other problem with these is that they always seem to crack at the very bottom. I don't know if microwaving them is a bad idea or why this happens but I always continue too throw them away too buy more again. I do wish they kept my fruit and veggies longer too but I had no luck with these containers for that.

I can buy these just about anywhere. Superstore for 4.99$ a package of 4

These are ok if you are looking for a single use product, I prefer to use Rubbermaid because they last longer. For me I find the lids on the Ziploc containers break on the second or third use, then you end up having to throw them away.
