You can also keep an eye on the
DisneyStore.com; they some times have sales and sometimes they clear out pins and a discounted price.
In truth, nothing is going to 'beat' the price on eBay where pins can sell for as little as $0.50 per pin (or less). As the PPs have mentioned, at those prices, they're most likely going to be scrappers. Scrappers is just the generic term used to describe technically non-legal pins. From everything I've read and seen, they fall into two general categories. The first are the straight knock-off pins (fakes). These are often the easiest to tell because the color, heft, feel, etc. are wrong. Imagine getting a pin of Ariel with blonde hair or Belle in a green ballgown. Those are pretty obvious problems with the pin. The second category are the over runs. Let's say a factory is contracted to produce 1 million pins, but instead they produce 1.1 million. Instead of scrapping the extra pins, they sell them on the side. Everything about these pins look and feel correct because they were made in the same factory with the same materials, but they're technical not "legal" because they were supposed to be scrapped. I don't think these can be distinguished from the ones you buy in the parks.
As Reddog1134 said, if you're going to do pin trading, you just have to accept that scrappers are out there and that you
will get scrappers unless you forgo trading with CMs. CM lanyards and the pin boards/books will have scrappers in them (probably a high percentage). In the end, you have to decide if having scrappers in your collection will ruin the experience for you.
The only way to probably avoid scrappers and still pin trade is to only deal with the "professional" pin traders. Personally I would be wary of the professional pin traders. These folks do not have to trade with you nor do they have to adhere to the Disney trading guidelines (e.g., one pin for one pin). I'm sure some of them are nice folks, but I would be cautious when approaching them for a trade because for many of them this is a business so they're out to get the most valuable/expensive pins possible from you. So if they will trade your pin for their's, that's probably fine. If they ask you go buy a pin or pins for them, I'd walk away. If you're new to pin trading and do not have a sense of the value (in terms of dollars) of the various pins, I'd avoid the professional traders.
In terms of finding less expensive pins, I would focus on checking out:
- Disney Store Outlet - there are a couple in Orlando and they often sell discounted/reduced price clearance pins and pin sets.
- Disney Store - I haven't seen much in the way of pins being cleared out, but it's worth checking out.
- DisneyStore.com - once in while they have a sale and they have pins in clearance. Disney Rewards Visa card holders get a discount.
- Walmat/Target - some of the stores near WDW sell Disney pins.
- eBay - I do think it's possible to find non-scrapper (or at least avoid the fakes) on eBay. Look at the descriptions and focus on ones that say things like the pin is on the card or in original packaging. With eBay there is no way to know if you're getting scrappers or not until you have the pins in hand.
