I always insist on USPS money orders, no exceptions, when selling anything online. They are hard to falsify, and easy to cash. Checks, even "Certified" ones, can be faked, and can take weeks to get back to the bank that they're written on. Your bank may initially credit your account, then after the check bounces, debit your account AND charge you a fee on top of that. USPS money orders can be purchased at any P.O. with cash or a debit card, and sent right from there by Express Mail with tracking. Any buyer that argues with this requirement is likely a scammer.
For shipping, UPS only ships firearms from UPS Customer Service Centers, not UPS stores. I believe that they require Overnight for handguns, which is about $75 or so. Putting a copy of the receiving FFL in the package is a good idea, but also have a copy in hand to show the clerk. The maximum amount UPS will insure for is $1000.
Be prepared for a little trouble at the shipper, as some don' know the rules and may have to call for advice. Give yourself enough time to deal with this. It's not a bad idea to call the shipper directly ahead of time to be sure you know all the rules.
Good luck.
