I think you have it pretty well worked out John. Business online moves at a very rapid rate, and there are an increasing amount of players on the field of online sales.
Finding your angle is difficult enough most of the time, but damn hard to keep it unique as others try to replicate a winning process.
You may not have the price advantage that you did before with your ties, but you do have the advantage of location.
I may well be proved wrong on this one because I have no stats to back me up, but I believe that most on sites such as ebay would prefer to buy from a local provider, or even one from the west.
Most have the perception that if it is coming from China then it is cheap and nasty, of course not always the case at all. I would be turning my marketing angle slightly to reflect the fact that I'm a trusted local seller, not selling from China whether you are buying from there or not.
Of course I am assuming here that you were buying in bulk, and not drop shipping...lol
It's horrible, but factually true, a negative pitch to highlight the fear of the unknown with a customer can generate a sale just as quick as a positive reinforcement, maybe even quicker in some cases.
Maybe even look for another supplier with different fashions to test another tie market.
You never know, maybe there is still a way of hanging on to your market, and of course if price is the issue then you could look at liquidation stock to get an edge.
