The silver lining of a slow sales week is that it gives you time to get the basics right. For instance:
listing new Items, which you're doing well
taking good photos, like on your clothing listings
checking Completed Listings to see if your selling expectations are current
checking unsold existing listings for ways to improve them.
Please take this with a grain of salt, as I only sampled a few of your huge inventory, but at first glance your photo lighting isn't good enough. This is cheap enough to fix with some professional lamps. Also the backgrounds aren't helping. The red behind clear glass would be good with proper lighting. But the items on wood table need white background instead, like the flat white background in your photo listings.
Also you will need to be more patient. The two items I looked at were not in demand, and those sales that were going through were going at 20-50% of what you are asking. Money off is all very well, but if only one of an item is selling each month, money off will not magic up extra Buyers.
Hopefully September will be better for you!
