Dennis, the freebies they're talking about are for admission to the trade show. This costs $10 in advance or $20 at the door.
Unfortunately, even if you score one of these from a vendor, you still have the matter of airfare (or lots of gasoline and Cracker Barrel meals,) hotel room (which start at around $120/night for rooms within a mile of the show site,) meals and, most important, refreshments.
And you'd certainly want to sign up for some classes and workshops. You can take all you want for $395 or pick-and-choose.
That being said, it's the best investment a framer can make in his or her career. Well, other than $25 for an introductory membership to the PPFA. (Or maybe it's really all Gobblety Goop.)
If you are in a purchasing position, for equipment or materials, you could conceivably save enough in "show-specials" to pay for the whole trip.
