IFC, Harbour City, Times Square, Langham Place, K11 and similar cluster brands and dining under air-con. Many stay open late.
Ladies' Market, Sham Shui Po fabric/electronics streets and Stanley Market are great for atmosphere and small buys. Compare prices; for pricey electronics prefer reputable shops and keep receipts.
Hong Kong generally does not charge a VAT/GST-style consumption tax (unlike many countries' tourist refund schemes). Some shops may run their own visitor refund promotions — terms are set by the retailer. This is not tax advice; ask staff before you buy.
