okay, the entire package of them (600) were shipped out today and heading my way. Should be arriving late in the week or at the beginning of next.
I will then pack everything into the smallest and least expensive USPS box, send you each an invoice and then print the label once you have paid.
I did not factor in the shipping cost from the manf. to me so price per pack is slightly higher than $0.60, right now I have it calculated at $0.68 a piece. I still think total shipping will be more cost effective once I get the total to you than submitting 30 separate shipping orders to them (plus not sure they would split it up anyhow).
Let me know if you have any questions, but you should have them in-hand by next week.
