Shopping was easy and being able to pay via Amazon is convenient. I do have to say autoplicity shipping emails and tracking webpage is behind. By the time they notified me that it shipped I had already received the products 2 days before. That's not a bad thing. It's always better to receive stuff before they said it shipped any day. Thanks Autoplicity!

So far--so good ! We'll see what we get and when, before making any final assessment of the deal.
