Other than leather stamping, or screen printing - does anyone have any swag or similar stations you can bring to a trade show or conference? Something that happens live and guests get a takeaway of some kind!

Hello!! I am looking for a US swag vendor that is FANTASTIC at logistics/shipping. We sadly have had quite a few hiccups with our current vendor on the shipping and fulfillment side so wanted to see if anyone has a vendor they recommend. Asks are that they can hold all inventory and that they have the functionality of a 'store' for us to place orders from. Thanks!
