Many of the pictures I post on this blog are for sale. See my Bid-or-buystore for further details!
Disadvantage of this: It's a pain to be redirected to a new site.
Advantage: I am a registered seller on bid-or-buy, which means they have checked to make sure that I am a real person with a clean record. Art works are generally sent to buyers via registered mail, and the shipping cost is included in the price.
