Anywhere to get real stamps at a discount?
They often have ads hanging in the lakewood shuls for $40-45. They also advertise in vivaser (lakewood daily publication) from time to time. You can probably ask to see them before or for references.
Odds of those being authentic are very slim.
Dunno, but I just bought several rolls for $47/each and every single mail piece was received. PM me for info.
Receiving or delivery isn't a proof.
