Some people sell Millions at Tucson but it takes allot of time, preparation, and money. I have a 10x10" booth in a soso location at a ok show and just the space cost me $4000 for 2 weeks. No lighting, no advertising, no signage, no showcases, or anything. I'm newer to the trade show seen so I will have to buy allot more things this first year out their and will be leaving it all except for my inventory at the end of the show in a storage locker. Being new to the Tucson show you have to spend allot more on advertising so buyers know who you are, what you sell and where to find you, most buyers go back to the same sellers in the same location year after year. Next year I plan on having a booth at 2 different shows one for 2 weeks and the other for 3 but those shows don't cost as much as other shorter shows can. At the AGTA and GJX shows depending on the size of your booth you can spend I believe $15000 or so for a 5 day show. By the time you add in buying or renting show cases the booth space, lighting, hotel or house rental for the length of the show, rental car, food, advertising, plane tickets, and all the little things it can really add up. We should have around 3mil in inventory much of it being rough and rubs on display at Tucson this year so the chance of having good sales is there but from what I here the first 2 or 3 years is a bit slower for new exhibitors because buyers who go every year already know what they want, who to go see, how much they are going to spend, and generally do all of that with the same sellers. Buyers might only perches a small amount from new sellers to test how reliable they are over the first couple years. Allot of people go to Quartzsite AZ for a cheaper show that time of year. Tucson is plenty big enough for a whole discussion on so hit me up if you want.
