Pattaya offers many kinds of shopping. You can imagine it is from bustling open-air markets that sell food and non-food items, noisy night markets, street stalls/vendors and local shops to western style department stores, supermarkets and upmarket specialist shops.
Bargaining - is expected everywhere except in the big department stores, supermarkets, malls and food markets. In toruist centres of Pattaya and Jomtien, the prices may be inflated to almost twice the real price to allow room for bargainning. Most shop keepers use a calculator so you can make your counter offer. Start at half the price and work your way up, depending on your bargaining skills and the will of the vendor. Remember that bargainning is norm here. Expect to pay from 10-40% less than the original asking price. While most department stores and large retail outlets have fixed prices, so bargaining is not applicable.
Purchases - in Thailand are mostly a cash basis. You can use credit cards in some stores but there are limitations and precautions. Use your credit cards only at the reputable businesses and with caution because credit card fraud is growing. Do not let your credit card out of your sight because someone might make more imprints. Major department stores and supermarkets accept credit card purchases but a few charge a 3% or more handling fee.
Smile - bargain with a smile and you will be rewarded. Many Thais work long hours, so they appreciate a smile and good humour - you'll get better bargains.
Beware of Touts - the Tourist Authority of Thailand warns against touting taxi drivers and tour guides who offer to take you shopping and receive commissions for bringing tourists to various places to shop. Often the experience is a waste of your valuable shopping time.
Export restrictions - be aware that it is forbidden to take images of Buddha, deities, and some antique artifacts from the country without first obtaining approval from the Fine Arts Department in Bangkok.
