Add the three items below to your basket to get the duplex unit (currently on sale @ Amazon for £53.33) for free!
Yes you can buy the printer for a few quid less elsewhere... and yes you can buy "compatible" ink for less than Epson version but the savings wouldn't buy you a duplexer now would it?
The instructions for the deal are under "Product Promotions" on the printers page but the links take you to other retails *NOT* Amazon. You need to use the links below otherwise the offer will not work.
