Amazon's Kinky Side

Has anyone here bought items from Amazon before? I spotted a chastity belt on their website—it’s a solid metal model with an MSRP of $140 but sold for just $17.70 ( … B00AQ8SXR8). Looking at the related links, other items have similarly low prices too.

I’m naturally a bit anxious and often view huge discounts with suspicion, thinking they might be scams or just inferior knock-offs of genuine products. So I’m wary.

Are these bargains really as good as they look? Or is Amazon peddling junk that’s only worth about $20?
