What is overstock? I've been asked to review something I'm unfamiliar with so I'm unsure what to do. Is this normal for a first review? I'm confused

I love overstock always shop there I get some great deals and their customer services really good especially in regards to the shipping if it's a large item

I purchased this Ruby necklace for my wife as a small ‘just because’ gift back in January. The selection and price for jewelry on overstock is wonderful. Beware of the quality of the chain. It was replaced soon after I received the necklace.
