Pattaya is not a good place to go shopping for hi-tech products such as cameras and computers, but for Pattaya's best selection of electronics under one roof, see the Tuk.Com (Com City, South Pattaya Road) listing below.
Foreign currency can easily be exchanged for Thai baht at the many exchange booths which can be found in all areas popular with tourists - there are even mobile exchanges/ATMs in specially adapted minivans that are set up as and when and where the need arises. Note that the majority of exchange booths will buy foreign currency but will not sell it - if you need to obtain USD (for example if you're going to Cambodia) use one of the larger branches of a major bank, such as the Bangkok Bank branch on Second Road (almost opposite Soi 6).
Beware of buying fake branded and designer goods, since these are likely to be confiscated by customs officers at the airport. Five tons of counterfeit designer perfume was crushed by a bulldozer in front of press cameras at the airport in 2007.
Central Festival is one of the largest malls in Asia. Opened in mid January of 2009, this sprawling complex has really put Pattaya on the map for grand scale shopping and dining. It is the best shopping mall in the region and now attracts customers from all over, adding to the traffic chaos of Beach Road. Fashion, electronics, health & beauty, kids activities and food are all here. Zara from Spain and Next from the U.K. are here with a cinema complex and bowling alley on the top floor, this mega-mall is styled on the big Bangkok destination shopping areas like Siam Paragon. The Food Loft has the best view of the bay and great variety at reasonable prices. The anchor store is Central Department Store itself, offering high-end designer labels from abroad and Thailand. A supermarket and budget food hall is in the basement. Enter from Soi 9, Pattaya Beach Road or on Second Road after the new View Talay complex.
Central Festival Centre is a large mall on Second Road across from Soi 2. It includes the Big-C department store, and an IT Corner with mobile phones and accessories but no computers.
Mike Shopping Mall is on Beach Road between Soi 11 and Soi 12, with another entrance on Second Road, and opens 11:00-23:00. The ground floor has many small stalls selling clothing, tourist souvenirs and many other inexpensive items; above that there's a department store; on the 5th floor there's a food court; and up on the roof (10th floor) there's a public swimming pool.
P.S. Plaza is at the junction of Second Road and Central Pattaya Road - Tops supermarket occupies most of the ground floor; billiards, books, massage, and a handful of other shops on the first floor; and P.S. Bowling on the second floor.
Royal Garden Plaza is a large upscale mall adjacent to the Pattaya Marriott Hotel on Beach Road between Soi Post Office (Soi 13/2) and Soi Pattayaland 1 (Soi 13/3), with another entrance on Second Road-look out for the plane in the wall. It boasts lots of decent stores, a good food court and cinema.
Tuk.Com (Com City) on South Pattaya Road is a new and predominantly IT mall. In the basement is a Tops supermarket, a food court, and various other (mostly clothes) shops as well as a spare parts department that sells a variety of electronic (e.g. transistors) and other parts (e.g. clothes washing machine lint filters), and the ground floor hosts an assortment of regular shops. However the upper floors are almost exclusively mobile phones (1st floor), computer software and MP3/video CDs (4th floor), and computers and handheld electronics (2nd/3rd/5th floors). Prices are significantly higher than in Bangkok.
