I am trying to get an idea of how Massdrop works. What really happens when you Request on Massdrop? If you go for instance to a Group buy for a product where The drop has ended and the following message is displayed: Want to bring it back? Request it! After 200 requests, well contact the vendor to re-launch the drop.So what happens when I click on Request? Does this legally bind me to purchase the item if the 200 threshold has been reached, and price negotiations with the manufacturer were successful? Or is it simply a means to signal intent for the product, but still leaves me free to choose whether to buy it or not?

The latter. It is simply used to get a rough idea of how many people are interested in it. Once there are 200 requests, you get an email from Massdrop informing you that you can now purchase the product.
