Mooching around on the net and came across this site:
ExpatFoodPattaya.com – Groceries delivered to your door in Pattaya
Mostly brit groceries (some Russian apparently), but also looks like decent meats and cheeses as well as prepared meals.
Delivery service, and they seem to have the Siambury stuff that I have heard people rave about.
Nationwide delivery but excludes Udon Thani, Hua Hin, and Ban Chang.
Tempted to give them a go. My only minor niggles at this point is that they do not seem to have an on line credit card payment system, so that means extra faffing about. In addition it seems they have to work out the delivery cost, so you order, wait for them to work out delivery then go do a bank (ATM) transfer (I do not do online banking apps etc).
If they had it a bit smoother with a credit card payment would probably have already placed an order....
anyway - anyone used them?
