Cappy, where do you get your bottles?
The 3 mL bottles I get from madvapes, the 6 mL I get from E-bay 6 ml LDPE Squeezable Plastic Dropper Bottles #100 - eBay (item 360366575405 end time Jul-12-11 05:25:30 PDT)
With both types I drill out the cap, and with the 6 ml bottles the end as well with a 1/16" drill bit.

the post office guys seem to miss those notes here in the boonies. either that, or they see my annoyed look in line when i have to trek to the post office for pick up
