How long to M&M's last?

They'll definitely last. As long as the package is fine and stored in a dry cool place, those things will last months, even years I bet.

Chances are they WILL have another groupon by then...but ya never know

In my house they'd never make it that long, but if you think you can resist temptation. . .

Keep them in the AC!

I saw that groupon too. I googled the same question and read that alot of people freeze them in the unopened package for several months with great results.

They only last as long as it takes for me to get the bag open.

Can you buy the groupon, and then redeem it closer to your date? Otherwise, they should be fine.

I decided to buy the groupon and I can redeem by Jan 22 so I'll wait as long as possible and then freeze. I better place a lock on the freezer and give key to FH because like you guys no M&M is safe around me lol

I also looked on the website for it and I can make it my wedding colors which is purple and cream and add our dates to it. So I'm going to buy a pound like this and then mix it with ones that will just be our colors so price isn't crazy lol

The coupon is good until March. Just wait and use it then.

That's great I thought had to use by end of Jan less time for temptation is always better lol

Yes they will last. I've had some for over 8 months and they were fine
