i have bought quite a few handguns from highly rated dealers. absolutely never any problems.
there may be a credit card fee per the dealer you are buying from, and most certainly be aware that now if i recall, gunbroker collects sales taxes for all the states, or at least, many of them.
i have also contacted the gun dealers in emails (after the auctions) to see what else they had available, and when i did this, and bought from them..??
NEVER any sales tax or credit card fee's, since those sales are not going thru gunbroker..
just shipping charges apply
