Most customers don't bother to do research, don't know that jelly is dangerous (just like the other examples in this thread) and when they use google to arrive on Eden's page, they'd click away when their ten second attention span waned if they didn't find the cheap jelly crap they thought they wanted. They'd just go elsewhere, and never learn the difference. So EF carries jelly, and it's up to reviewers and sex educators and bloggers to slowly try to educate people.
I'd never use or recommend jelly, but I do think some of us overreact to it a bit -- yes, it's bad, but if someone's smoking 3 packs a day, living on diet soda and fast food, and smearing endless chemical crap on their bodies every day in the form of cheap hygiene products, then what the heck difference does the jelly make, really? I think people need to choose healthier choices in all areas of their lives, not just in sex toys.
