I'm selling a bike with a spare set of wheels to someone, and I need to ship it. It's been a while since I've had to do that. as I recall, the cheapest option is fedex ground. I'm not sure if that's still the case.

Also, I'm wondering what is the best way to package the bike and wheels.
Should I get a bike box and a wheel box and tape them together?
should I get a smaller bike box and just put the frame/fork, and somehow squeeze the handlebars in there, and then get two wheel boxes and stack those together?

I feel like the latter option might be better, because they charge based upon L+H+W, and the closer the package being shipped is to a perfect cube, the more cost effective it is.

anyone who's done this have any input?
