What's outstanding AC?
I have three cases paid for and undelivered. And they are big ticket items. I am now (a little bit) worried, based on your experience, although mine are more recent purchases.
I too have found Simon very helpful when I have been emailing him, but that's on the purchasing front not the tricky customer service issues (which are just as important if he wants to build purchaser loyalty).
I assumed his long lead times were to gain enough orders to place a big enough bulk purchase to get the discount he had promised and to pass that through and take his cut. Maybe he's not getting the numbers straight off that he had hoped. Maybe he's having trouble with suppliers or logistics companies. All usual teething problems with a brand new online retail business. Simon ought to keep you in the loop even if not good news on the lead time of your second case. Otherwise, his would-be buyers like us will lose confidence in his business and stick to the big guns.
