I'm thinking of getting some poly mailer bags off amazon but not sure what size to get. For those that have shipped with them before, is 9x12 a good size or 10x13 better? A box of 100 seems crazy, but that's all I can find and the local stores don't sell the white/gray bags.
Depends on what you're shipping. If you get the bigger ones, you can always fold them down smaller.
I think I fit 5 diapers in the bigger size, but the more you pack in the more the cost of shipping as well. That package was definately over the 13oz limit and I had to pay extra to ship it. Still less than the flat rate box though.
