Input: Consider Input: I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...

Input: Consider Input: there is a taste of sugar substitute, the aftertaste turns me off, I've even tried using a little bit of milk in the mug before hand to hide the taste. It didn't, so i'm just using Swiss miss powder and a little milk to make it a creamier hot chocolate before using using my keurig.

Input: Consider Input: This canned organic corn is great. Sweet and plump, and being organic is added bonus. Inside, the can lining looks JUST LIKE Eden's BPA free cans, but so far I can't find the consumer service number of the company to verify if their can is BPA free. At least I don't see the white plastic lining in these cans. I'm just hoping these are BPA free, then these are totally awesome!
