Jenson USA

I’m new to biking I’ve only had Walmart bikes and I’m ready to step it up to real brands I saw a few bikes that I had my eye on but they are a few hundred dollars cheaper on jenson usa . Com I was wondering if this is a trusted place not a scam I don’t have much money and don’t wanna lose it all over a scam . Looking at a gt or giant bike around 1400 on jenson but on the gt website it’s 3500 and the gt is 1800 it seems kinda suspicious considering the price difference
