Is the Hershey chocolate discontinued? Which one is it?

I have to sell some chocolate bars for my 4 year old son, it is fundraising for my son's Christmas party at his daycare. I heard that Hershey, reese, Oh henry is discontinued? Or was is it just the little bars that were for Halloween that are discontinued? Please some advice, I dont want to sell anything that could harm someone if there is bacteria or whatever in them. Thanks
