"what apps to use when thrifting. I am hoping to get an iphone soon and have no clue what to do with it :)"
I have an iPhone too, and I wouldn't know how to behave without it! I really only use a couple apps when I'm thrifting.
#1. The most obvious one is the eBay app. With this one, you can check current listings, completely listed, and you can filter out just the sold items. That's a very nice feature. You don't have to sift through a bunch of unsold items to see how much your item COULD sell for. I use this one literally every time I go out shopping.
App Cost: FREE
#2. If I strike out researching on eBay, or if I'm trying to research a seasonal item, I turn to the Terapeak app. I can get data back a full year on it. You have to have a paid Terapeak subscription to get a year's worth of data though.
App Cost: 99c
#3. My all-time favorite "app" to use while I'm out thrifting is the text message. Every online seller needs to get themselves at least one good seller-buddy. I will often send pictures to other seller friends to see if it's something I should pick up. I've made good money this way by buying things my friends have okay'ed. I've also saved good money this way by leaving behind the things my friends have nixed.
That's the only apps I use. There are others out there, but I don't know anything about them.
ScoutPal is good for amazon sellers. I don't use it because I don't sell on Amazon.
Amazon's app is good for toys and other items that are still in their boxes.
There are several different barcode scanner apps out there, but again ... I rarely sell items with barcodes, so I don't bother with that one either.
There are also apps for garage sales, Craigslist, auctions, and other venues like that. A quick Google search showed me Garage Sale Tracker, which looks interesting. It helps find and organize garage sales AND consignment/thrift store events. Might have to look into that one once I charge my phone.
There's also one other thrift store locator app that I have used in the past, but I can't for the life of me remember what it's called. I only used it once or twice because it was stupid and couldn't find the thrift store that I was sitting right outside of, so I deleted it from my phone. Probably no big loss that I can't remember what it's called.
Anyone else use any other apps that I haven't mentioned here?
