Exactly when will you be in town and for how long? Also, where will you be staying, visiting, working??
Sending stuff to your hotel won't work. The vendor has to show that the merchandise was shipped out of state or out of the country. I went through a sales tax audit and had to produce UPS receipts. Are you visiting any other states on your trip??
The gun shows would be good to visit. I sell at about 8 a year. Also interesting if the timing works out is the TRW Amateur Radio Swap meet which is on the 25th of May which sounds too soon for you. Its held outdoors in a huge parking lot with about 800 to 1000 vendors. About one-third selling ham radio stuff, one third computer stuff, and one-third other stuff: tools, toys, you-name-it. They've been doing the show for over 30 years so they get a great turnout of vendors and buyers. I'm the idiot selling flashlights in the sun. Also sell knives, multi-tools, magnets and more.
Anyhow, let us know when you'll be around, we'll find all the hot stuff to do...literally. Fire season came early this year. We weren't done with smog season yet.
