Hello, nice to meet you! I'll typically send smaller-value trades in an envelope and higher-value trades I'll ship in a bubble mailer with delivery confirmation.

I am around most of the week and will ship as soon as we confirm the trade.

For the cheapest way to mail with delivery confirmation use this link:

It is currently $1.93. I keep getting packages where the sender is spending $6 to ship. You don't have to do that.
