This is such a cute idea, especially if done tastefully. I’ve seen it done a couple times and the guests seemed to love it. You can find the candy in different shades of your wedding colors and store it in vases, mason jars or other clear containers.

Buy the candy at a bulk or penny candy store and remember you don’t have to get it all at the same place. There aren’t many of these penny candy stores left, but if you can find one in your area, you’ve hit a goldmine. I did find this site, Candy Warehouse (http://www.candywarehouse.com/ ). Their prices might not be as good as a local store, but it’s a good alternative.

It would be really nice if you could get metal candy scoopers too. I don’t know what these usually cost but I found some for about $2.50 each but you have to get at least 12. Depending on how many you need, I guess that’s not too bad.

There are also these plastic scoops, which cost about the same, but you can buy as few as you’d like.

It looks like there’s this rental company (and I guess others do it too), who will rent you all the supplies necessary and even bring the candy. Not a bad idea if you’re short on time and patience but it might end up costing you more than you need to spend.

The last detail is the container your guests use to get their candy home. You can use plain white lunch bags, which are easily found at Target or Meijer and are very inexpensive.

I hope you find everything you need, and at a good price.
Good Luck!
