“I’m buying more,” Ms. Bowen wrote in one chat about the morning-after pills, after noting that she had already purchased a few for her children in May, in response to a leaked draft of the Supreme Court decision published by Politico. “Reminder,” she texted another of the group chats, referencing an earlier discussion about buying the contraceptive. Then she ordered six additional pills, paying about $10 each.

“The rules are the same for both my kids,” said Ms. Bowen, who has a daughter in high school and a son in college. “They’re to let their friends know that we have the pills and if one gets used, we need to replace it with a new one. I didn’t become a crazy buyer hoarding hundreds of pills, and I’m not trying to supply contraception to the whole town. I’m doing this because now abortion won’t be available and I’m worried that this sort of contraception soon won’t be either.”…

Even before rallies and marches could be organized, the immediacy and access of the internet provided an outlet. The founders of Stix, a vaginal and reproductive health company that sells products such as pregnancy tests, yeast infection products and emergency contraception online, said that demand for Restart, its morning-after pill, surged by more than 600 percent in the 24 hours after the Supreme Court announcement. A pill costs $38 and has up to a 20-month shelf life.
