Interesting contrast on the facts with the Dell Canada case against Quebec Consumers Union a few years ago in the Supreme Court of Canada. The consumers were on the low moral ground – they found a mistake in a Dell catalog that offered a laptop for about 15% of its regular price. When Dell corrected it, the consumers found a deep link and sent it around. Dell refused to deliver the computers. When the consumers brought a class action, Dell pointed to its arbitration clause. The Supreme Court upheld it, though the decision has been criticized in some quarters (in part because Quebec’s consumer arbitration rules are pretty restrictive). But it was hard to sympathize with the consumers who were trying to get away with dishonest conduct.

In Dell they had a click-through agreement, though…

There are some articles in The Business Lawyer 10 years or so ago that are still accurate SFAIK re what’s enforceable and what not.
