TaoBao Spree timeline question.

So I made an order with TaoBao Spree to get some Krad Lanrete stuff about two weeks ago. I haven't heard anything from them for the second part of the order. I know they have to order it and get it sent to them before they get back with me. But I am getting a little antsy, and was wondering if anyone here had ordered through TaoBao Spree before and if so what was there wait time between first payment and second payment. I think part of what has me so anxious is that the print I want was already limited quantity and I want to make sure I am able to get it, though I would assume they would have messaged me before now saying they were unable to get it. Let me know if I am over stressing it or if maybe I should contact them and find out.
