A word of warning to those using 'that' online auction site

[Olddust]

I have shipped international from Canada to USA and others. As well as received from outside the Country. I use gunbroker, and will ship permitted items, but as stated buy others before about 30% of US sellers will not ship items to me. Why I don't know. Numrich will, so why not “bobs guns of Kansas” I guess having the biggest market sown up makes doing business elsewhere a chore.
