I too don't really mind if the cards are sent in envelopes - I fully understand the $$ involved when sending out. From memory when based in AU, I was spending about $40-$45 on postage if I did approx 30-35 cards. (This round if I'd sent from AU, would have been $33.00.)

I'd love to always do the max, but have to take postage costs into consideration for every road.

That being said, I love receiving from all over the world - postage marks all over the actual card or envelope, I don't care, just as long as they fill my mailbox in greater numbers than those awful bills!!
