I would like to find some thai buy & sell websites have tried to google it but only english sites come up any ideas out there

Pretty much depends what you buy & sell.

Real estate & cars pretty much have their own. (one2car.com, taladrot.com, pantip has realestate and probably more buy & sell too)

Otherwise from what I remember Hunsa.com & Sanook.com have buy/sell sections

Have you considered the classified section on thaivisa.com ? Quite easy to navigate and narrow down your search fields.

Bhat & Sold is also not bad

thailand2hand is also a buy sell site i think, can't be bothered to check lol

Try this:

I think the OP is trying to find Thai websites not English websites.

Websites in Thai or websites in Thailand? Unless he reads Thai well, being in Thai isn't much good but he doesn't specify.

The hint was in the original post: " have tried to google it but only english sites come up"

The product on offer matters .... (or the product he is looking for). Without that information it is fairly useless to try and direct him to websites. If he is looking for Thai language websites a simple clue would be to use Thai as the search language (ie: input the search parameters using Thai.)
