You have some beautiful and very expensive items for sale.
If I was looking to spend several thousand pounds on your item, I would like to have seen a Returns policy, I'm sure a No Returns on say your £2,400+ watch would put most people off. Remember you cannot refuse a case for ' item not as described' it could result in damaged items being returned for a forced refund, it does happen !
You say you struggle to make daily sales, but I see you have successfully sold 2 very expensive items in the last few days, that's brilliant. If you look at the Discussion Boards many sellers are reporting low sales, yours in comparison are very good !
Check out other sellers selling the same item, see how yours compares with their price perhaps list your a little lower, as most buyers will search through Best Match >> Lowest Price.
Your photos are great, your item specifics great, but one thing I noticed and would always put me off buying, did you use AI for your description? Personally, I would always write a personal description it is also more relevant to the exact item you are selling.
Your sales to me so far look very good, and I would say well above average for the luxury items you are selling.
