Anyone have advice on where (Bangkok area) I should go/contact to purchase 20 air conditioners? HomePro offered me a project price of 10% off sticker price.

(16 x 9,000 btu, 2 x 12,000, 2 x 20,000)

I recently bought two air con units from LAZADA on line they have some good discounts and promo codes they delivered to Isaan at a cost I think I was 300 baht per unit (shipping gets added to the bill at the end before you confirm payment) but this may be less for Bangkok. They do a lot of promotions worth having a look at the website its in English and they have English speaking call centre you can contact. In total I had 4 deliveries and all seems ok. If nothing else it will give you another source for price comparison.

until you require any after sales service and with 20 units for sure you will need this

from my own recent experience on a big ticket item after they have taken payment for your discounted super save

bargain products they become very difficult to deal with it like they have disappeared of the map

ie 3 months for a refund on a large freezer far from the 5 day turnaround they advertise
