So I got the real DL on the mysterious caps yesterday. Turns out that the reason they have plenty of the (ostensibly more expensive) nipples, and almost no (ostensibly cheaper) caps is not due to economics. Or rather, it’s all about economics.
The caps, they gots to pay for. Buy them, ship them, sterilize them, and stock them. The nipples are donated to the hospital by the company that makes them (who I shall refrain from naming), in the hopes that parent and child will grow attached to them and use them once the patients get sprung from the hospital. Product placement at it’s most vexing.
