I ordered this pump, and had it canceled. I thought I messed something up, ordered again carefully, and had my order canceled. I email support to find out my mistake, and learned they have no inventory to fill orders. Why is it still selling in the site only to be canceled in the background? Since I can not believe the website, I asked support for information when will new stock come? Can I get on a wait list to be notified? No answer is available to either question. I think this is a great product, but the business is not running transparently.
