Millions of pieces of mail are in the system daily. Many, many of which contain illegal items. The government isn't going to spend thousands of dollars investigating, pursuing, indicting, etc every person who has a package with a couple hundred dollars of gear in it. There isn't the money or resources for that. They will spend money on the big fish who are trafficking huge amounts and evading hundreds of thousands of dollars in taxes, especially the dumb ones who advertise their illegal activity making investigation easy and worthwhile, like Musclehead320 or WFN, etc. Order domestically, use encrypted email, a VPN, have everything shipped Priority mail (basically all sources do), and just don't be stupid and you won't have any issues.
