Puzzle warehouse

Hello puzzlers! I have to thank you all for reigniting my love of puzzles. I have been looking at the puzzle warehouse website and I would really like to order from them. I live in an area without USPS home delivery but I can't find information about how they ship. Has anyone ordered from them and remembers if it was USPS or another carrier like FedEx or UPS? Also what do you all think of them?
