Samsung Flip 6

Hi

We are returning to Thailand on Jan 2nd and have recently bought a Samsung  Flip 6 from ao.com in the UK it is still in the unopened box and I do have the receipt. I paid £749 but I have changed my mind and probably won't have time to return it. I understand they cost a lot more in Thailand and was wondering if anyone would be interested at £700 or 30,100 THB

Its in yellow which from the pics looks nice and has 256 gb internal storage.  Is advertising here OK or is there a website someone could suggest. 

Thanks

PS we will be in the Pinklao area from the 2nd to 6th, then Ko Chang for 2 days then Chiang Mai for about a week, returning to BKK on around the 16th.  Collection only and payment ideally to my UK bank account if buyer has a UK account or Cash from an ATM
