Last caps I purchased (A-Zoom, 5 per package), cost me $17 for .380 and $15 for 9mm. The ones in your photo seem much better quality since they appear to have spring loaded primers compared to the simple rubber primers on the A-Zoom versions plus you get 6 vs 5. So comparably I'd say the price is about right.
yeah...they are WAY too high....Bradis is cheaper but even there $15 for 5 pieces that really don't do much and serve little to no purpose...they aren't a necessity by any means and so I don't understand how they make any money at those prices
