My wife and I have been canning for over 20 years and we re-use our lids each year. Occasionally a jar will not seal (about 1 or 2 per year), but we have never gotten sick from our home canning. However, one must be prudent when opening a jar so as not to bend the lid unduly.

∙ 10y agoIt is not recommended that you reuse any kind of grocery store jar for canning. Canning jars are made differently and the glass is less likely to break. If you use recycled grocery store glass jars they may not withstand the heat and pressure of canning. Also, if the reused jar doesn't seal properly, your food will go bad and could make you and others very sick.

∙ 13y agoCanning lids should not be reused to reseal a jar. That is, once a lid has been used, it should never be reused for canning/preserving purposes. It can be used, however, to store opened foods in the refrigerator.

Can you stack mason jars?
You can stack filled jars if you place them in the boxes that the jar were purchased in. The screw on rims should be removed first.

I personally only stack my jars two high to avoid too much weight causing seal damage.

Let the canned jars sit for a day in plain view first. A couple of indications: You might hear the jars making a popping sound, after a day you can take the bands off of the jars and if the lid is loose, check the ingredients, possibly the lid did not seal.
