Nice try MysticGohan, but you have to have a physical copy of the Catalog. There is a reason they are honoring the price, and that is because they go out to Best Guests, which are typically those people that spend about $1,000 on their Target Red Card / Visa each month. Oh, and they've already corrected the online price, so they can deny to honor the price on those grounds as well.
You can try to bring in the printout of the online catalog, but I wouldn't be surprised if they do not honor it. Unfortunately, I work in the department responsible for proofing the design/layout of that Catalog, and wish I would have caught the mistake. We're not trying to be asses if we don't honor the price, you just have to look at it from our perspective, that a mistake was made, and we're losing $29.99 for each one of these units that moves out the door.
