After I bought my first recent pair, I was buying my second, when during the checkout, up pops an offer to add another at good price. YOUR offer, *not* my request. But when I added that other pair, the price was much higher than the offer on your page. I spoke with someone who could only repeat over and over "you can only use your discount on the first pair." Not what I was asking. Since I was NOT trying to use my discount, but only responding to YOUR offer, this was not helpful.
