Sales/marketing techniques in Singapore

The most commonly seen forms of sales/marketing incentive techniques in Singapore:

Pamphlets – everyday I see armies of people stand in street corners, escalator landings, and shop fronts dispensing thousands of tons of printed pamphlets to all and sundry. Even at a recent computer show – there were probably more people handing out pamphlets than actual gear to look at.
Product demonstrations – I see these on street corners and in the high-end department stores. Often cookware and cleaning tools. Good entertainment value.
Free gifts – like McDonald’s kids meals, some stores seem to have rolling gift-giving programs as a default “customer service” activity. There is so much gift-giving that the consuming population now seem to expect it. But the gifts are usually pointless trinkets. Perhaps most people’s houses are stuffed with these gifts?
Sales, promotions and offers. These are usually price discounts, or – you guessed it – free gifts!!! I sooooo do want another cheap, badly made, virgin plastic panda that glows in five different colours…
Credit card loyalty discounts – restaurants offer 10-20% discounts if you pay by certain credit cards. I like this.
