But have tips to share....
Going: get up early, scour newspaper, pick ones that interest you, be there 10-15 min. early; HAVE CASH...preferably small bills
I only go EARLY, no later than 8AM, done between 9 & 10
Look over things CAREFULLY
DO NOT buy things you don't need! It is easy to get caught up in a bargain...
THAT being said, I do buy larger kids clothes that are in great shape at great prices...
Bring drink & snack in car...
Selling: Clean garage out week before...
Place ad early in week but ONLY to run the days you have it. BE SPECIFIC ABOUT WHAT YOU HAVE TO SELL...I always mention big ticket items specifically, I mention the brand names of clothing & toys, as well as clothing sizes.
I ONLY have sales Fri-Sat, 8-1. Fridays are big here, afternoons are so slow I don't feel it is worth my time. And sometimes Sat is so slow I have considered a one day sale only....
Begin setting up several days ahead of schedule. Get LOTS of tables/shelves to display. Organize by category. HAVE EVERYTHING PRICED. EVERYTHING SHOULD BE CLEAN & WORKING, unless noted. I DESPISE sales w/ no prices, and disorganized, dirty stuff. YUK.
Get change the day before...roll of nickels, dimes, quarters, $50 in ones, $30-50 in fives. Fanny pack (I hate 'em...but) are best $ holder.
HAVE HELP...DO NOT HAVE KIDS AROUND IF POSSIBLE...at least the first couple of hours.
I generally do NOT bargain early in day, but as things slow down I do. Sat. everything is half price! (I am known to change prices on the occasional item that I am not willing to part with at such a low price.
I am a believer that I want to GET RID of stuff, make a few $, help others out. So I price fair, but low. Really, what would YOU pay...DO NOT price it higher than that!
Now, Little Tykes/Step One large items--cabins, climbers, etc., sell for about 50-75% of retail if in good shape. Other items stick w/ 10-25% of retail, but they better be in very good shape!
(Now, my accountant used to tell me garage sales are a waste...and I have to agree w/ him now that I use It's Deductible to itemize donations. I got $3000 in deductions last year...WAY more than I would make at a sale! It gives you MUCH higher value than you could ever get at a garage sale...that being said...the lure of cash money....

)
Good luck everyone!
PS Call Goodwill BEFORE your sale to pick up the Monday AFTER your sale!
