I have. I assume since the cashier at CVS pharmacy sees my pull up in a car, they just assume you're 18 I guess or they really don't care.
They really shouldn't care.
Unless you're an idiot it's pretty much well-considered that it's better to have children have safe love than unprotected love.
If you're a cachier at a pharmacist and someone underage comes up with condoms and you refuse to sell it to him because you don't agree that he should have love, well fine, but know that you've sent someone underage away who is almost definitely going to have love, but now unprotected.
All the pharmacists around where I live will sell you condoms regardless of if you are underage or not.
And then you can get them for free from doctors and
family planning clinics.
And my school nurses at my previous secondary schools would provide free condoms too and my College nurse does too.
She just has a large bowl of them for you to enter and take from, you don't even have to talk to her.
At the beginning of the year when I joined the college she came around to tutor groups, explained her role as a nurse and gave out free condoms.
