title: Woocommerce - 2 free samples, then a user must pay
body: <p>I’m building a website for a client which will run on Woocommerce, and need to offer samples for each individual product. The products are floor tiles, and they'd like to offer samples of the tiles. However, to avoid a situation where users can order massive amounts of tiles for free, they'd like the functionality to be such that each user of the website can order 2 free samples, thereafter they have to pay (for example £5 per sample). With perhaps some other conditions as well, but the “2 free – then you have to pay” is the basic functionality required.</p>
  
  <p>There are a couple of Woocommerce Samples plugins I've found, but none of them offer the paid functionality. Does this sound like something which is possible? </p>
