Just wanted to say Thanks for all the advice. Things that came to fruition as warned/advised.
1. Folks showed up in the dark. We are talking 1 1/2 hour before it started. (8:00 till 12:00).
2. Learn to speak Spanish. (Messican's) I did and fluently replied "ocho" when asked a size for a pair of skates. She seemed impressed but did not purchase them.
3. Haggler's, yep I was prepared and caved a little towards the end.
4. Everything was cleaned, priced and on tables. (We borrowed 6 tables from my son's church).
5. Professional re-seller's. They did not waste anytime. Picked thru, purchased and moved on.
6. Yesterday must have been the "Day of Yard sales", they were everywhere!
7. Sold a shotgun shell re-loader in a hurry on FB, had 14 replies in 15 minutes.
8. Had a gun case and FB pulled our ad and had to remove the item. (a-holes).
You guys/gals were correct, a lot of work but we cleared $571. I had never been to one much less participated in one. There is a cult following of yard seller's!
