Is there a way to make unlimited money online?

This seller committed something like what we call predatory pricing but instead of setting the price very high. It is considered illegal because it violates the antitrust law. It is also unethical because it will hurt the consumers not physicalty, but financially. Although it is a rare concept in competition law, it is still unethical.

I think a lot will depend on the full story like why is the adult child still leaving with parents? Anyway if it was me I would handle it this way. Rather than charge rent from my child, I would allow him to live rent free but he has put aside the amount of money he would otherwise be paying for rent it into either a savings or a retirement account. This way in a few years he/she could have saved up enough money to become a home owner.

Is this some sort of trick question or aptitude test? Anyway if yours is a real life scenario, 7 teachers will have to pay $6 each for 7 tickets which will equal $42 and summing that with the $2 each of 40 students which is $80 comes to a total cost of $122. That was not rocket science was it?

There are a few ways of handling this, either you can open up a package immediately and check for damages so that you can give the package back to the delivery service so that they may contact the seller on the matter, or you can go contact the company responsible for selling the merchandise, these contact infos are usually present in the website or fan page, they usually take it back and provide you with another model but it will probably take some time to do so

Under the Lemon Law in Singapore, which falls under the Consumer Protection (Fair Trading) Act, buyers can make a claim for a defective product within six months of purchase. Consumers can request for repair, replacement, reduction in price or a refund, says Seng Choon, adding that the law applies to goods and services sold online by a registered Singapore company.

Since the store is not giving any refund although it was their fault, you can report it to the local trading standards department because it was part of a statutory right of a customer. You can send them an email and notify the shop about what you are about to do. That way, maybe they will do something about your ordered products.
