Wow. I bought 6 tubes of the Durvet back in November for $22 total, delivered. Bought a couple tubes of a similar product at a brick and mortar TSC for $4 each at Christmas.
The only place that I can find Ivermectin for sale in Indonesia is online from some vendor in Bandung. The price is IDR300,000 (USD23.00) for two 12mg tablets.
$4 at tractor supply...
