You can get the organic Grade B maple syrup for less than half that price... there are a few links floating around for the web sites for that. Here's one.
I get $100.00 worth and get the free shipping and have enough syrup for over 40 days.
They say the lemons will last up to 2 weeks in the fridge. I have 2 dozen in there for over a week now... I had to quit the Master-Cleanse while I was sick. I hope the lemons hold up for another week or so.
