>>10231661My guide is always just look at the box. the last 4 or 5 digits of the serial number is the price in yen.
for example, this MG Exia. On the box, is a serial number. the last for digits is 3800. so Exia is 3800 yen. I baseline convert 100 yen to 1 USD. so, a good asking price for the MG Exia is 38 USD. of course some stores will have some overhead, so I usually put it with a margin of 5-8 USD.
that's how I look for deals with Gunpla.
