There are downsides to really thinking about it, though. "Hmm... $.92/piece seems pretty high. Am I really paying a dollar every time I have sex? Does that make her a prostitute? Weird. I thought we were in love."
Plus you can find brands you didn't know existed. "Rusty's Brand Ultra Thick." I didn't know that existed, but it's only $.83/time-doing-it.
The weirdest thing was, as a force of habit, I still did the thing I do in normal stores where I bought a couple other items so the checker wouldn't think I was only interested in sex. I'm thinking about sex AND printer ink. See? Not a sex addict.
Amazon wasn't fooled either. I had a bunch of stuff in my cart but as soon as I added the condoms, all my recommendations instantly turned into sex toys. "People who bought condoms also enjoy blow up dolls." What? No they don't. Those are completely different demographics! If I want a blow-up doll, I'm not super concerned about having half blow-up babies.
Next time you're buying printer ink and want to get the free shipping, I highly recommend ordering a 24 pack of Rusty's Ultra Thicks.
