Tengu Models have announced a price increase for May 2011.
From their announcement:
Due to a number of factors we’ve had to take the decision to increase the prices on some of our packs of figures and resin kits. The price rises will come into affect early next month and will be preceded by the website being off-line for a few days whilst we make some changes to the site. We plan to close the site on the 9th of May, with the price rises coming into effect when the site re-opens. There will be no change to our flat-rate postage charges.
All figures and resin kits currently available from Tengu Models will remain at their current pricing for the remainder of this month and the first week into May.
