I bought a Daihatsu Mira Custom about a month back. It has the same engine as the Daihatsu Move. I also bought the oil filter from Filter House, Defence couple of weeks back for Rs. 390. don't know why he charged you 750. And let me guess, they also offered you Micking oil 5w20.
Genuine air filter was not available and they had a local one and they were asking for 750. I didn't buy it.
Some items are way overpriced at Filter house. But at least you get the original thing.
