Yes I have experience buying fridge's here.
I once hired some girls to work in my restaurant and the restaurant provided housing but not the fridge. The girls were so cute and were a great addition to the staff so I went and bought a fridge at the cheapest place here in Phuket, it's called "Supercheap" and it's a huge store with no air con thats why it's called "Supercheap" it cost 3,500. for a medium size one in a beautiful blue color.
