InstaPrice lets you snap photos, add price captions to them and share those via social networks. You just take a photo and attach a price to it, then share it with your friends via social networks (i.e. Instagram, Facebook).
Furthermore, it allows you to pick a cover and use it as a template to showcase the product and its pricing. Once that's ready you can share it everywhere online and easily start an Internet sale. You can share it via Facebook, Skype, WhatsApp, Twitter, Instagram, eBay or even e-mail/SMS/MMS.
