ive been lucky and have never received one white envelope.(ive done my fair share of ebay buying as well) However, i have also been on both sides, buying and selling. I think there is a bit of a double standard when it comes to this issue. Buyers want cheap shipping and maximum protection for their purchase(bubble mailers) i would fit into this class too and would be mad if i received a card in an envelope. However, i would imagine that most card sellers are in a similar position as i am, this is not a full time job, just a way to make a few bucks on extra cards. Since i dont buy bubble mailers in bulk, they usually cost me close to $1 each. You add that to the average of $1.25-$1.50 it costs to ship within the US, and your already at over $2 cost. i dont know about other parts of the US, but Gas In CA is ridiculous, and even going 3 miles to the post office could cost close to $2 round-trip. Dont get me wrong, anything over $3 shipping in my eyes it too much, but in reality, it really is not. Us buyers almost force sellers to keep low shipping prices, which might be a reason why many are turning to PWE.
Just a thought, not taking sides
