When I needed to send something back, I figured out how much it would be to send my Astrolux MF02 back to China it was $92 dollars with USPS (by far the cheapest option I found). UPS wanted $157 dollars. The flashlight cost $86. So if I sent back the flashlight it would have been $92 - $30 = $62, if I was refunded the full amount of my purchase it would have been $24 dollars that I would have received back or about 73% of my original transaction amount lost. So unless the light was pretty expensive (as you mention) it wouldn’t really be worth it. I would hate to see how much it would cost to send something like the BLF GT70 back…
