Do you find the uninterested/non-chalant attitude works better than the general-friendly attitude? Also, do you change your demeanor depending on the type of person running the sale? We're usually just plain friendly, but thinking about it, the "this stuff is all junk" attitude might be a smarter plan of attack for the older moms that don't know the value of anything.[/QUOTE]
Remember this : you only have one chance to make a first impression.
I'm finding out it always pays to be friendly up front with a nice hello and a couple of key phrases like "well you picked a beautiful day for a yardsale" or if it's overcast say something like " I hope the weather holds out for you today" It always softens people up especially women if they have little kids when you compliment the children with a phrase like "what a little angel" or what a handsome young lad you have there . If the kids are selling ice tea or lemonade always buy a cup and give them a tip and make sure the parent sees you. Say something to the kid like here's a tip for such nice service.
It really depends on the situation on weather or not I'll show great interest in something. i usually lean towards showing little interest in anything. i try to work it so it looke like I'm doing them a justice by buying the stuff they no longer want.
Sometimes I can get get a feel for what I'm up against by looking at the prices on non-gaming stuff at the sales. For instance if I see a coffee pot priced at $10 as opposed to $1 or a picture frame priced at $3 instead of .50. i can pretty much tell if the seller is reasonable or unreasonable.
The older moms are somewhat easier to play. They tend to have no sense of value on gaming related stuff. Sometimes you can turn the situation in your favor by making them think that there gaming stuff is of little value. With phrase's like "wow this stuff is older then dirt" " i guess nobody wants this kind of stuff anymore, i see this kinda stuff at all the yardsales I go to" Or "maybe my son or nephew might play this .... er uh ....i don't know they're all into that new xbox stuff" If you could just get it into the sellers head that there is no demand or value to their stuff you're setting yourself up for the bargain deal. In most cases they really want to get rid of it , cause no one is using it and it's just collecting dust.
If you show a strong interest in something the seller will try and hold you to a higher price cause they know you want it. IMO it's best to show little interest.
People like to be stroked a little it makes them feel good. If you can manage that with the people you're dealing you'll come out a winner. I always put on a facade when I'm yardsaling, cause actually I don't care if it rains on their yardsale or if their kid is cute or if they have a nice day or not. i just pretend I do, I want to try and hustle them out of something I want for the lowest price possible. I'm not trying to mean or anything but I work for a living, I don't have an abundance of cash and I should get the most I can for my money. I know what fair and reasonable pricing is on stuff, but I'm not in this for the fair and reasonable, I'm in this for the ridiclously cheap, and realistically these are strangers we're dealing with, most of which we'll never see again.
I don't know if this approach can work for everybody, but it works for me as evidenced by some of the deals I've gotten. The more yardsaling you do the easier it becomes to develope your own rhytym kind of speak. You eventually learn from mistakes and capitalize next time around. You'll develope a style that works for you and once you know it works the only thing you can do is improve on it to get better cheaper scores.
