I was going to purchase from this website because the website had a very low contact box price. However, once the processing and shipping were added, I decided to go back to my regular purchase place of Walgreens.com and wound up paying about $29 less. Even though Walgreens' boxes advertise for more, with their frequent 20% discounts, and discounts for buying a year at a time and free shipping, it was a better deal. Not saying this website is bad, or that I wouldn't look here again when price comparing, but I like that Walgreens has faster shipping, marks their boxes with R and L and is cheaper this time around for me.
