Price 物価

I bought a light poncho

A poncho is useful when we go to the mountains and it rains suddenly, as I can wear it over myself and the backpack. Otherwise I have to cover the backpack with something else to keep it dry.  Also, a poncho covers my camera.

Some of our trekking friends liked it too, and I was asked to get the same poncho for them.  That was two years ago and the price was 1600 yen.  Recently another friend saw it and asked me to get one for her too.  I checked everywhere on the internet but the cheapest I could find was 2500 yen.

There were some small improvements, but 900 yen more in just two years?
