I only have about a year on some that I just used two weeks ago and it was still just as good as the day I bought it. So I can only answer for one year to this point. Just make sure you keep it closed up if it is opened I can't speak to that

I don't think so, but it has been almost a year since I purchased, so I cannot be certain.

I can't say for sure. I do know that it was at least one year in the future. It had a good expiration date, and they are a good price.

Yes it's good for one year or till you use the $100 up. I've used the $100 card for many years and it works great for me.

I buy in quantity's to last over a year with no problems. I find no "best if used by" date listed.

Call the company when in doubt, most are 1 year. We had one for many years with no problems, that is why I bought another one.

Yes, the ones I just bought are good through 2015. They do not list the sell or use by date on the Amazon page. That might be helpful.

Most natural products will last one year. I have never had a problem with Eminence Organics products, but I use them up before a year has passed.
