Would potential customers mind if I sold my 11x17" posters by shipping them folded, in letter size documents? It would greatly decrecase postage (to $2-$3) because I wouldn't have to deal with mailing tubes, which I annot procure at affordable prices.
JSYK, the posters are printed on relatively thin gloss instead of cardstock, kind of like magazine covers would be, so they do fold easily.
The selection would depend on what I have left over from previous local cons haha;;;
