I have noticed a delivery charge on Chinese imports, it was very common just over a year ago to see FREE SHIPPING on nearly everything coming in from China ,not anymore for most things, the M91 I'm watching on E-bay has a $45.00 shipping fee.
Bruce, I still see quite a few of Jin's eBay listings offering free shipping. As far back as I can remember he has always had some listings that had shipping added on as well, so I don't see that much has changed .... yet!
I think what is currently going on in Hong Kong may bode poorly for our hobby items however, as that may not simply up total prices as tariffs can, but could actually cut off access completely.
Let us hope that cooler heads prevail, but history does have a tendency to repeat itself in an ever escalating spiral, so I'll not be surprised if it turns out badly for all concerned.
