Is there a stockist, in Chiang Mai?

Preferably Sirimankharajarn area.

Rimping stock the capsules at all their branches.

Those are the Nescafe Dolce Gusto at Rimping. Totally different.

Central Airport Plaza has a large array of coffee machines- I believe they might stock them. Either way their kitchen section is worth a browse.

Expect to pay about 3 times the price they charge in normal countries..

Central Festival have them but I expect at a high price.

Even back home, people order them from Amazon or Ebay because they are so expensive in the shops. Knowing the price charged for Lavazza coffee beans here, I'd say it would be well worth having someone mail some to you.

A 10kg carton of beans is the first thing I order when we go back home, once they're in the case I fill it with whatever else I need.

Bought these for my nespresso machine for when I'm running out of capsules:
