This is my first WPPI. Do the vendors there typically offer discounts if you buy there, or is it a typical product demo booth but no on the spot buying type of show?
Some have "show specials" but usually they are some weird obscure packages of products to get people started. Most of the labs or album companies do not have any kind of deals. But smaller product companies trying to get their foot in the door will have discounts and such. Other companies like ThinkTank, LowePro or other gear manufacturing booths will have some kind of special, sometimes. The retail stores (like Adorama) usually do not either.
