How do you ship? I always do First Class mail with DC, but I have noticed frequently I send something off after something I order and what I sends makes it to other people before I get mine. Do most people do first class or parcel post or media? Just wondering the common way to ship...

I ship small things first class and all 'bags' priority.

WSS! First Class is often just as fast as Priority but things over 13 oz within the U.S. and over 4 lbs internationally have to go Priority.

I didn't even think about bigger things (I don't sell them often) but all bigger bags I do flat rate boxes.

Flat rate is always priority...so I use that with f.r.e if the item ends up being more than $5 to ship (like something small but heavy)-- like a jjb hip.
But mostly I use first class. It's cheap, d.c via PayPal is free.
I never used media mail...it's illegal to send anything that isn't cd, DVD, etc that way.
And parcel is pricey.

I use first class mail for under 13 oz and priority for over. Unlike priority, first class is supposed to take 2-5 days rather than 2 days.

Under 13oz, First Class.
Over 13oz usually a flat rate envelope/box. It is worth the few extra $ to send it priority vs parcel. You can't use media mail unless there is only media items in the box, dvds, books, cds, ect.
