I'm in the market for a new trials helmet. I've been to all the usual US sites and find not a great amount of deals on right now, which is surprising given it is end of the season. Splat Shop in the U.K. has a nice Airoh TRR S helmet in my size and color on sale for about $208 including shipping to the U.S. That same helmet is on RYP "on sale" for $299. However I've read other threads to be wary of ordering from overseas due to a bill coming from the shipping company a few days/weeks after the delivery with customs duty owed. Is this something I should worry about?
