New beauty test tube?

I am curious as to when and if there will be a new auto delivery sign up through qvc? I can't remember when my last shipment was, I checked my orders and it seems as though I have recieved one more recent than what is showing. Either way I dont know if my auto plan is up already. I don't see a new one available to order. Any info on the test tube would help, I don't want to miss the next one. Which really brings me to my next question, why is it that they only do the auto delivery on this product for short term? When I first ordered it I thought it was until I decided to cancel then I figured it out. Thanks for any help. Dina
