Another reason you're probably not getting many sales is that most of your items are in the wrong category. I doubt people would be looking for them in jewellery and travel tickets. I'd get on and change those categories because if eBay finds out you've listed in the wrong categories (you are violating the search manipulation policy), they will end all your listings and possibly sanction you. I'd also remove the website addresses, including the link to Amazon, because you are also in violation by doing that.
