I've always been a bit unsure about buying a slot on one of the showcases on Etsy, as I've not read particularly good things about them in the forums.
However I eventually decided to bite the bullet last Friday on the Fall Wedding Showcase and thought I'd share my experience. Coincidentally that was the night I was on the FP as well - typical!- so it's hard to tell which results have come from which!
The item I featured in the showcase, the
Fizzy Bubbles Bracelet is one of my best sellers as a bridal piece.

It didn't sell on Friday.
However I did get 4 enquiries about custom orders for bridesmaid accessories. 2 of these have become definite orders for multiple items, which is fantastic!
So would I pay the $15 again for a showcase?
Well, I wouldn't say definitely yes, but I may be tempted to do a wedding one again, as I do think it brought extra exposure to my shop. It's not something I would rush into though, as I think $15 is pretty steep for one days advertising.
