Prius Accessory vs PriusChat Shop

Are these the same organization/Company? I got an email ad from the former on the 9th of May that offered 30% discounts on Prius accessories. I was interested in the fog lights. When I put in the discount code at check out I calculated that the discount was only 18% and not 30% as stated! So I dropped them an email hoping that they would respond, stand behind their advertising and give me the 30% discount. Two days later I got a new advert/email from them with the wording changed to "Prius Accessories - Up to 30% Off" Still no personal response to my email. Thought the forum ought to know about this and shy away from giving them any business!! I will do all my accessory shopping through the PriusChat shop!! Thanks.
