If a company prices a product erroneously, then (in the US) do they have to sell the product for that price, if someone buys it at that price? If a company prices a product erroneously, then (in the US) do they have to sell the product for that price, if someone buys it at that price? Or are they allowed to correct the price and not sell for the erroneous price?
It will vary by jurisdiction. This is a complicated area of law, but usually an advertisement or a display of goods in a shop is not an "offer" (in the contract law sense of the term), but an invitation to treat (or "invitation to bargain" in the US). The "offer" is the shopper saying "I'd like one of those please" or putting the goods on the band for the till. The "acceptance" is the checkout girl saying "that'll be ..."
Depends on where you are, and likely also on what they knew when. It is entirely normal to order some goods (like perishable food, or custom-fitted furniture) before it is produced. The contract may or may not include advance payment. Most jurisdictions require some sort of intent for fraud, so the non-fulfillment would not be fraud if circumstances beyond the control of the supplier prevent delivery. The question of civil damages and repayment is distinct from criminal fraud charges.
In fact, the first recognition of the First Sale doctrine came about precisely because a publisher attempted to do something of the nature of what you suggest. In Bobbs-Merrill Co. vs Straus, the Bobbs-Merrill Corporation attempted to enforce the following restriction, printed on the inside of a book it published: "The price of this book at retail is one dollar net. No dealer is licensed to sell it at a less price, and a sale at a less price will be treated as an infringement of the copyright." They made the mistake of attempting to enforce it against, among others, R.H. Macy and Co., who they then had to take to court - and lost. This established the First Sale Doctrine, which then later (in 1976) was codified (in 17 U.S. Code § 109. Textbooks recently tested another element of this; in the 2013 case, Kirtsaeng v John Wiley and Sons Inc., the Supreme Court held that the First Sale doctrine trumped a notice forbidding selling a book outside of a particular territory or region (Kirtsaeng imported textbooks from Thailand, where they were much cheaper than in the US, and resold them at a profit in the US).
The question is always, would a reasonable customer be confused into thinking that the two are the same, or that there is some relation or sponsorship or attribute to one product or firm the rightful reputation of another. That is always dependent on the specific facts and the specific market involved. So-called &quot;famous&quot; marks get extra protection. The exact markets involved will matter. Any stylizations such as colors and typefaces may matter. Logos may matter. I can't say if one of those specific names would be found to infringe on the other.
It would be a violation of 18 USC 1001, which is the law against making false statements to the federal government. Paul Mozer, who was a Salomon Brothers trader, received a four month sentence for doing something along those lines in 1994. Bidding on something implies an intent to pay for the thing, which in this case is a falsehood: in so doing, one "falsifies, conceals, or covers up by any trick, scheme, or device a material fact" (that you don't intend to pay for the thing).
Unless you have caused loss to the customer by making the typo, the answer is no. Obviously, anyone can attempt to sue anyone. However, for the court to accept their claim/charge for processing it needs to fall in one of these buckets: They had a contract with you personally and you were in breach of it — obviously this does not apply in your situation; You committed a crime — looks like this is not the case either; You had a duty of care towards them and committed the tort of negligence. This is what the customer must be referring to — making the typo could be regarded as negligence, especially if it caused actual harm/losses to them.
The price is not one of the terms and conditions of the CC-SA license. You may chose to attach a price to a derivative work (which you have the right to create under license section 3.b). But any person who receives the derivative work legitimately (from you or from someone who got it from you, directly or indirectly) must get it under the CC-SA license, and has the right to redistribute it, and may do so at no charge if that person so chooses. Also, you may not impose any copy protection or other technological measure that would prevent exercise of the reuser's rights. Whether selling a work that may be redistributed freely is good business is your decision.
A company can charge each of its customers a different price if it wishes. Providing this discrimination is not on the basis of a prohibited reason (race, sex etc.) this is not illegal.
