Probably everyone here knows that PayPal is horrible to eBay sellers, taking the buyer's side practically every time, and no amount of photographic evidence can convince them that you the seller really did ship the item purchased.
Enter Bitmit, an eBay clone that operates in Bitcoin. Does anyone know how fair the are with regards to their escrow service? How does a seller prove they shipped the item? How does a buyer prove they didn't get it? I'm a little hesitant to sell on Bitmit just because it is not nearly as established and "safe" as eBay.
Ebay/paypal disputes always fall down to proof of postage. There are very limited options that they accept as 'proof of postage'. For example in my country (Australia) the only accepted method is Australia Post Registered which comes with its own tracking number. Although it's recently been upgraded, that product used to have no online-tracking but ebay/paypal could call Australia Post and verify with their internal records things like the package details, destination, delivery status etc.
Can seller provide proof of postage?:
YES: --> SELLER WINS DISPUTE
NO: --> BUYER WINS DISPUTE --> FORCED REFUND
I imagine bitmit has a similar system. If you are ultra paranoid, you could film yourself packing the item up for shipping. This might be useful if disputing the condition of the arrived item. You should obviously pay a little extra for shipping methods that have some kind of tracking, online tracking would be the most convenient as I'm not sure bitmit mods would actually call couriers and postal services around the world like I know ebay/paypal has a whole department for.
