The company named Maplin has recently launched a Facebook page that lets you browse their product offerings without having to leave Facebook. Still yet, to complete a purchase, it will continue through to the Maplin site to conclude the transaction.
Most pages on Facebook do not offer an ‘in page’ shopping experience. You can see the store front from Facebook. If you want to buy something, or need further information then you are redirected outside of Facebook to complete the transaction on the brand site.
