less expensive
Step-by-step explanation:
If we assume the supplies in Nearland have a constant price of 15 NRD, then the cost in USD last year was ...
(15 NRD)/(3 NRD/(1 USD)) = 5 USD
This year, the cost is ...
(15 NRD)/(5 NRD/(1 USD)) = 3 USD
The cost in terms of USD has gone down.

Additional comments
Usually, exchange rates and local prices are related. If the supplies are produced in the US and sold in Nearland, the producer may want to maintain their pricing in terms of USD. That is, a supply that cost 1 USD last year would have been priced at 3 NRD last year. This year, the same supply, for the same 1 USD cost would be priced at 5 NRD. In Nearland, the supplies are more expensive than they were.
The real answer is, "it depends".
