Note, I'm just looking for a mild weather sleeping bag (above 50 degrees) not something that I'll need to keep me thru a cold season. Something light for traveling in summer.
Look at your local Target store or someplace, you can find all kinds of sleeping bags. They're good sellers here, not because people go camping that much, but for friends/family who are couch-surfing which is often sleeping bag on floor surfing lol.
I have a Coleman I like, it's too heavy for backpack carrying, but fine for traveling with a car. It was $30-odd.
