For some tracks there are even speedrun/lower-cost guides for online degrees through places like WGU. They except transfers from online courses as well. You can do it cheap, especially if you get tuition reimbursement.

I just found out my state (Massachusetts) offers associates programs at any state CC for anyone who doesn't already have a degree. For adults over 25 the program is called MassReconnect. I'd have to look into transfers, but I imagine those could be transferred to WGU towards a 4yr or post-grad degree. Some of the CC programs can also be done all (or mostly) online.
