OP here...
Thank you for all the replies. I'd like to be able to take a lot to a consignment store, but I am in a rural area and don't have that option. We do have a Plato's Closet in the next town. I haven't been, but I've been wanting to. The kids have a few name brand clothes that I will take there.
I just can't get past the idea that it would be nice to have some extra money. DS is on the golf and basketball teams and DD will probably be playing volleyball next year. They always need food money for away games. Last year I kept yard sale money, ebates money, and inbox dollars money in an envelope and used that for all those little extras. If I didn't have the yard sale cash it would seriously cut down on that fund.
So, I will suck it up and have a yard sale. My plans for keeping it as simple as possible:
1) Group like items together and make one price sign for them all - for example: all DVDs are $2, all books are $1, all clothing items are $?, etc...
2) One day sale only. My sale will be on a Saturday from 8am-noon.
If anyone has more suggestions for making it simple, I'm listening.
