Build a website that allows free samples to be added to a cart

Hi there,

A bit of a broad question but I’m hoping to get some advice about how best to approach a build. I have a client that needs a lightweight CMS driven site, that allows users to browse various products (paper stock) and request free samples. I assume an e-comm model works best, so they can fill a cart, they checkout and my client gets pinged their details along with all the samples they want?

Can I just build a basic e-comm site and remove payment, or have everything as £0.00? Or is there a simpler, better method you would suggest?

Thanks for any advice, much appreciated
