This is a weird ask...we don't even know where you live so the stores can vary. Yes, retail stores tend to upcharge to make a profit, this is common. I personally would be more concerned about the type of protein vrs semantics on pricing, unless you are on an extreme budget. Sorry to hear you got scammed online, but learning experiences happen and stick to reputable suppliers online and that should not happen unless you had a virus on your PC or something, maybe use a prepaid card if you are super worried. I am sure there are fitness stores in your general area? Try there, then find a product and research online. Good luck!
