RockinB,
CostCo sells little 'condiment cups', small plastic containers and they also sell lids that go with them. You can get, I think 2500 cups for around $20. The lids run a bit less. You see these in the fly shops for customers to put their flies in, and one cup will hold a dozen size 10 wooly buggers, several dozen size 14 dries.
For shipping, the United States Postal Service will give you, for free, no charge, shipped direct to you for no moneey (did I mention that it's 'free') priority shipping boxes in several useful sizes. You can order them from the USPS web site.
Some old newspapers for padding, and you are set to ship anywhere in the country for the current flat rate fee of $4.90. Charge $5.50 for shipping, and it will cover the cost of the shipping and the little plastic cups/lids.
Don't make this hard...
