Same problem here!  I think they will  fix it and honor the 30% of with $20.00 purchase since that was what the offer stated to begin with.  Since it say so in writing it is their legal duty to honor it. We shouldn't have to go anywhere else to find one that works at a different cost to us   False advertisement is against the law and Rendo has been very good with honoring their offers so, I wouldn't panic.  I am sure they will make the corrections and reinstate the original offer.  :)
