That is about a 25% drop from retail price which is pretty steep. Yet we do have to keep in mind that they most likely will sell yours at a higher price than $3300 in order to make a profit.
Most pre-loved fine jewelry listed on websites usually has a ~10-15% drop from retail price. Yet, due to the current situation (demand, inflation, price increases), that may vary. I'm seeing on
Fashionphile now that the small love bracelet is pretty close to retail price, yet most of them are in excellent or giftable condition ranging from size 15 - 19.
However, the combination of 2 factors may lower the price more than usual:
1) yours have been worn for quite a bit
2) And, your size of 15, the smallest size I believe, unfortunately may not sell as well as the more commonly bought sizes for average-sized wrists. (Same with shoes, size 7 and 7.5 sell the best because that is the most common shoe size for women).
For example, I do see a "very good" small love in size 16 and 17, but it's only about a 6-7% drop in price.
I have not sold to Fashionphile before so I'm not sure how they work, so I have a couple questions:
1) Do they just give you a quote and don't tell you want price they're projecting to sell it for?
2) Did they tell you what condition they judged it to be at? (ie. giftable, excellent, very good, etc.)
