The reason to buy says, "over half a million subscribers save hundreds a year". This statement could burn them in court if proven to not be a factual statement.
I would surmise that it could be shown that the half a million subscribers paying $480 a year each, (240 million total) may not save hundreds a year. The least they would have to show for a forgiving jury would be that subscribers saved a total 100 million in personalized boutique purchases and general shipping. A demanding jury would require 340 million in savings. I would wager that argued by a savvy attorney the statement could be read as a misrepresentation in advertising. It would also be based on how it read at the time of original subscription, so there wouldn't be much value in changing the statement now and only provide more validity toward it being a misleading statement. The defense would argue that people read the the info on the right, understood the terms and checked the box in agreement. The prosecution would argue that the claims in bold of so many saving so much resulted in more making the purchase, which was a false misleading statement.
Sales people make these types of claims all the time over the phone or in person to get a sale, putting it in writing is a huge mistake, and online retailers shouldn't be so brash.
