Currently Evermarker has them on Amazon.com for $34.85 with free shipping to prime members, plus they are currently offering a discount of 30% off one or more items by entering code GJBHTIA4 at checkout with some restrictions.
I did receive this item free of charge, and all opinions are of that of my own. I was not asked to write a review and chose to do so on my own. I am not being compensated for my post or for any items sold.
