PLEASE BUY AT THE CONVENTION!!!
The people who put on the convention NEED you to.
Vendors will not come back if they do not have a good weekend there.
Would you if you were a vendor?
Those booths cost a pretty penny and the trouble to load it all, drive it there from great distances, unload it, set up the booth, run the booth, take it all down, load it back up, drive it home and with the added expense of stying in some hotel usually?
Homeschoolers really do not think about the trouble a vendor goes to and the money the spend to be there.
So, if you don't buy there- they will be discouraged and maybe not come back.
This is especially true at the smaller fairs.
