Ruggies Ruggies charges a large "processing fee" and won't let you see the order before you hit send internet

I ordered 8 Ruggies for $10 and they tacked a $15.90 processing charge on my order along with the tax. The firm asks for your credit card info and then processes the order without you ever being allowed to see the final total so you can't change your mind. There was no phone number or email address to contact about the order. This should not be allowed. The order came today with no invoice - just the 8 Ruggies and an egg slicer (my free gift, I guess). This was an expensive lesson for me - hope other people are luckier.
