I didn't even receive the item I wanted...Lyst would capture my funds and hold them for several days then I'd receive an email about how the item wasn't available and then I was credited. Despite this, the item wasn't removed from your site for several weeks where I tried purchasing it 3 times, all with the same experience.
When I tried contacting your customer support the link was dead and I eventually gave up due to frustration. If an item is no longer available, either state that it is sold out or don't even bother having it as an option. You're an upscale retailer, you should be able to maintain a user friendly interface.
