So I was looking at Switch Lites on groupon goods because if you join Groupon Select you get 15% off purchases and free shipping for being a member. When I put the Switch Lite in my cart and went to "my cart," a green banner appeared at the top of the screen that said "Get $50 off this item." The promo is actually 50% off your first purchase, up to $50. You have to join Groupon Selects to get the promo. But here is why this may be YMMV. The promo didnt appear at checkout so I did a live chat with customer service and they were super nice and they placed the order for me and applied the $50 promo. The total came to $154.41 charged to my card.
This promo will lock you in to 6 months of groupon select @4.99 a month with the first month free which comes out to $25 spread out over a 5 month period. My GCU expired and I buy so many games that the 15% off all purchases and free shipping works for me. This may not be for everyone.
