I, like anyone else, am a cheapskate. The thought of paying $20–$25 per domain to the previous owner plus a $7.49 transfer fee on each to Go Daddy makes me cringe a little, because it would be only about $22 to just register the domains from scratch (if they weren't already registered).
Sure, Go Daddy provides a free one-year renewal on each transfer, so there's some value there, but I'm still wondering if there's a way to transfer the domains to my control without paying any transfer fees.
