What's a good discount for something used?

They say your car loses thousands in value the minute you drive it off the lot. Seems these days, other stuff may not. I see Savers charging close to the original price on some things. Lots of stuff on goodwill.com goes for over half the original price...and they don't even guarantee that it works! I try to pay no more than .30 on the dollar since you never know how much "life" is left in the product and usually have no way to return defective items. (Of course, I prefer to pay much less.) Still can't get over people who will pay too much for used stuff. Are they new to used or just don't care what they spend?

Took a foray into a pawn shop

Even though I love bargains and all things used, I'd never been in a pawn shop before. Just seemed like some sort of shady, dark world I would not be equipped to navigate. I mean, there's the three balls, the connection with crime and sketchy characters. But, that really didn't seem to be the case (except for the balls). I went in because I'd seen a telescope listed there on craigslist.com. I've been looking for a telescope, hoping I can employ it in bird watching (not to mention, I've always kinda wanted to get a better look at the stars). The place was in a safe area and the merchandise was in good condition. This one seemed to specialize in tools and I might go back for the miter saw they had. There wasn't all that much merchandise in the store, but what they had was well organized. They were asking a bit much for the telescope. I probably should have got the guy down another $20 (I paid $60), but I'm not good at bargaining, especially when the other party is likely struggling financially more than I. However, my "not new" telescope is in great shape, has all its parts and I'm happy to have gotten it in one quick, easy trip (been looking at estate sales and thrift shops for months and haven't found anything). I'll try going to more pawn shops in the future.
