Continuing the discussion from HTML tag abuse thread:
Not sure if this is 'WTF' in the usual sense.
In my post with the keyboard, it shows
Sale: $15.89 + $5.99 shipping
You Save: $33.59 (68%)'
But amazon shows this promotional text:
Special Offers and Product Promotions
Your cost could be $0.00 instead of $49.48! Get the Amazon.com Rewards Visa card and you'll automatically get $60.00 off instantly as a gift card. Learn more.'
Amazon's special offers & product promotions use the base price of the item, rather than the current sales price to calculate how much you'll save.
