I was just thinking about this, this morning and was wondering if anyone has been here but....
Fuzziwig's Candy Store in Clinton Crossing Outlets always has a bunch of color M&Ms. I always took this for granted b/c I worked there when I was 16 and had to clean up after people, haha. But just in case anyone is thinking about doing this for candy buffets, etc., I thought it would be a good way to save on shipping. The M&Ms themselves are probably expensive but no more so than through the website.
