And yes, Orange Tree Samples is aware that some folks have been signing up for the Group Buy and making purchases after the GB officially ended. The reason it's still being kept open is due to requests from a number of GB participants who asked for some extra time to complete their purchase due to things like waiting for a paycheck. Consequently, if this is your situation, Orange Tree Samples is giving you with a little extra time to complete your order. But be aware, they need to close this up as soon as possible, so the opportunity to complete your purchase at the Group Buy prices may be closed at any time without prior notice, after a number of orders from folks who have made requests have been completed. So, if you're order isn't completed at that point, there will not be another opportunity. In other words, please complete your purchase as soon as you can.
As far as folks who have snuck in to the Group Buy since it officially closed, it's no big deal and their orders have been and will be honored. I suppose if someone only becomes aware of the Group Buy today, you can always try registering and see if the system will still let you purchase. If so, your order will be fully honored. The same goes for anyone who already made a GB purchase and wants to attempt to make some last minute additions. Again, there are no guarantees, because the GB has officially ended, but while Orange Tree Samples is waiting for some transactions to complete, feel free to go ahead and attempt to get the GB discounts.
There will be a notice on the GB landing page when everything is shutdown and at that point you'll no longer be able to put discounted libraries into your shopping cart and complete a purchase.
