Do you need cash in Thailand?

Some. Malls and hotels take cards, but stalls, markets and shared vans want cash — and locals mostly pay each other by QR.

Can you get a tax refund on shopping?

Yes — 2,000 baht per day per store, a P.P.10 form issued at the till against your passport, and customs inspection at the airport before you check in.

Why is the price for foreigners different?

Because it is the published rate, not something decided at the window. A national park charges a foreign adult 200 baht against a Thai adult's 20; the Grand Palace is 500 baht for foreign visitors and free for Thai nationals. It is printed, it is set nationally, and there is nothing to negotiate.

Is there a limit on how much cash I can carry in or out?

Bringing baht in is unlimited. Taking it out is capped — 50,000 baht per person for most destinations, two million for Thailand’s immediate neighbours. Foreign banknotes move freely both ways, but anything above USD 15,000 has to be declared. You will still see 20,000 printed in older official guidance; the central bank’s figure is the one that governs.
