A multi-layer department store with just about everything. There''s quite a wide selection for different budgets - especially for those of us who cringe at prices at home (Norway). Good quality (and name brand) clothing at set prices - no bargaining activity here. Staff are more than willing to help and most can speak English. There''s a permanent sale of sorts on the 6th floor - from Tissot watches to baby push carts with discounts from 5% to 70%.
Once you''ve made your selection in say, British India, you''ll need to follow the salesperson to the cashier. Tourists get a 5% discount when initially paying (you just have to fill out a very short survey form) - no passport necessary. And then you get a 5% discount coupon for your next purchase. Then you can either lug the stuff around to Calvin Klein, or drop them at Bag Deposit.
When you''re done for the day head for the VAT refund (7%) area, in the store, if you''ve spent + 2000 Baht. Passports are requested, but I only had my driver''s licence which they accepted. Check the receipts next to the form before signing (as the purchases are recorded in Thai). Remember to fill out the form on the same day as the purchases. You get your actual refund (minus 100 Baht service fee) at the airport - be sure to follow the signs before going to check-in, and have the purchases on hand for inspection.
