Just to clarify because the info is spread out over a number of threads, this is the math/pricing I'm operating under (from Greg):
"A box of 100 is $65, plus $25 for FedEx Ground, which brings the cost to $.90 per bag.
A large envelope and postage for 5 bags is $2.50.
For a 5 bag minimum, the cost will be $4.50, plus $2.50 S&H, for a total of $7.00"
So in summary 5 bags=$7.00 and 10 bags=$11.50
Edit: Ok so the math is not quite what is posted above. By my and Greg's calculations I should break even at 5/$7. It sounds like $13 is closer to breaking even for 10. How does 5/$7 and 10/$13 sound to everybody?
