This game seems a bit stingy with stamps( although generous with other gifts). Right now I have plenty of coins, 46 potions, a mailbox stuffed with valuable items that are taking over 24 hours to arrive, but NO STAMPS!! I wish there were easier or more ways to earn them.
Hmmm, yes, I know you can buy them with "real" money, just trying to avoid that for now. in my opinion, we should be awarded a stamp for gifting, rather than being charged a stamp.
