Last two times this happened to me the retailers honored the posted price without argument. It's online, they posted it, they are responsible for their website. That being said, it's what the law is. Should they honor the purchase? That's a different question.
Sale Above Advertised Price
Section 74.05 of the Competition Act is a civil provision. It prohibits the sale or rent of a product at a price higher than its advertised price. The provision does not apply if the advertised price was a mistake and the error was immediately corrected.
Section 74.05 does not apply in respect of an advertisement that appears in a catalogue in which it is prominently stated that the prices contained therein are subject to error, if the advertiser establishes that the price advertised is in error. Also, if an advertisement containing a price error is immediately followed by a corrective advertisement, this section would not apply.
Where securities are sold at higher prices on the open market during a period when a prospectus relating to them is still current, the section does not apply. Finally, the section does not apply to the sale of products by or on behalf of persons not in the business of selling those products.
It should be noted that the section applies only to an advertisement of a product for sale or rent in a market. Accordingly, it does not appear to apply to representations in other forms, such as oral statements and most labels, as do most of the other false or misleading representations and deceptive marketing practices provisions. Of course, section 52 and paragraph 74.01(1)(a), the general provisions, may still apply.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
