What are some good marketing techniques?

Have anyone heard or experience any marketing scam? What are their techniques? Are these marketing "tricks" acceptable? (eg. Google "Inextron" or "Aowa" cases)

• In Asia, refund of any purchase is typically not allowed in any store. Especially in Indonesia, this rule has been "taken as an opportunity" for some stores to create a marketing scam, to make the potential buyer as if they have won a grand prize from a lottery that they have drawn in that store. This "free" prize that is claimed to be worth for $1000-1500, is not actually free. Customers have to buy a second product (min. purchase of $800), with "misleading" information that this purchase can be exchanged with lower-price products in 1-2 months, as a requirement from the Social Minister. The "confusion" created by comments, praises, personal questions by 5-7 salesman to this 1 potential customer, with an addition to "swiping" of customer credit cards without their approval but at the end they sign it. Moreover, the products that they finally got for $800 (claimed to be worth for $3000), are actually for better brands are only worth $500 the max. They have mark up the prices to mislead the customers. However, in the "transaction forms" that the customers had to sign, there is a statement that "any goods purchased cannot be exchanged and refunded", and "I as the buyer made this transaction without any force from anyone, and I made this purchase consciously", that make the customers are "weak" in terms of law. Especially that the customers pay $$$ for goods that actually they got, but the WAY they sell the products are not right.
