I fear this is going to be a shot in dark, but here goes...
A few years ago I got for my mother a Lolita Lempicka solid perfume. The case is in the shape of a golden apple with a crowned frog (i.e., frog prince) sitting on top. She passed away last year, and the apple was one of her things that I took. It came with one refill, and the sales associate where I bought it said that they would have refills in stock.
As you can probably guess, I haven't been able to find them since. Has anyone seen refills anywhere?

I would not want you to think that nobody paid attention to your question, so: I also searched everywhere I could but I can't find refills only. Just a couple of apples together with the extra refill (on eBay), just like the one you bought for your mother.
Maybe that is the only solution: to buy a new apple, maybe resell the empty apple to someone who collect frogs (and there are a lot of those, I noticed) and keep the two solid perfumes for yourself.
