I live most Winters for some month in Thailand and here I want to share some experiences with you, which may help you having an easier time here … it is mostly for people who spend over four month here a year ..
Btw I have a Motorcycle In Thailand info page at my website under https://www.kalka.org/thailand/motorcycle
Shopping
While most people think Thailand is a shopping paradise, it is actually quite the opposite. In Europe and the States I am an Amazon junkie, here you will have a hard time getting good things. For example a coffee machine that cost 350$ in Germany cost about 1100$ here. The same model and this is just one of many examples. Taxes reach from 100-600% .. Do not even try to get proper high end laptops or computers here, they won't sell. Better to find people who bring you this stuff from the States. There is nearly no chance to get a modern good dishwasher here and for a Tempur mattress that cost 2000$ in Germany they asked me 5800$. Yes you can buy a lot of cheap junk and some nice cheap clothes .. and amazing food …
Btw bring cash or use N26, I love this bank . (http://www.n26.com) they are the only ones who do not charge when you pay with their credit card and give you a great exchange rate … ATMs here charge 220bath extra and max you can get is 30k bath .. most credit cards charge 1.7% exchange rate .. good exchange place is Superrich (https://www.superrichthailand.com/#!/en)
A note Thailand sellers love to invent prices and write (1000$) now 300$ you save 700$ or 70% while it costs probably 150$ at Amazon ….
Online Shopping is about 5-10 years behind Europe, I think more 10 …
Cheaper in Thailand
