Why reels price better
A factory reel can be rolled, forklifted, strapped and loaded without anyone touching the cable. That handling advantage is worth real money on a large lot, and it is the main reason a tagged reel clears a higher number than the same footage in loose coils.
When coils are fine
Portable cord, welding cable and short cut lengths are routinely coiled and banded. A neat, banded, labelled coil with the print visible is perfectly saleable — the problem is a tangled pile, not the coil itself.
Loading realities
Reels over 48 inches need a forklift with the capacity to lift them, and a trailer with a deck that can take the point load. Coils can be hand-loaded but take up volume. Say which you have, because the freight cost moves the net number more than most sellers expect.
Keep the packaging intact
Do not cut banding to count layers, do not remove a returnable reel's lagging, and do not stack coils under other material. Every one of those decisions reduces the handling advantage you are being paid for.
