It wasn't until I got these I saw there are quite a few offerings for them online at
mymms.com, where you can get Light Side, Dark Side and general Star Wars M&Ms, dispensers, bowls, tins and such. If you're inclined to have a big May the 4th celebration, or you just really like M&Ms, you can even order 10lb bags of them.
Mine arrived in a very nice sealed foil bag. Inside the M&Ms were still quite cool with included reusable freezer packs, even in the now-warming-up Texas heat.
Here's what I got:
Star Wars Gift Box with M&Ms. These are the generic ones, not Light or Dark Side specific.
A
Star Wars logo Glass Bowl, and 1lb of Light Side M&Ms.
