If you live within a few states, there is no need to upgrade to Priority mail, so save yourself some money. ABC did research on this and found that packages often get to their destinations the same day, and sometimes Priority got there later. If you live across the county, PM may be a better bet. I live in VA and get my packages in the same amount of time, no matter which one I choose, so I always stick with the saving myself $3 =)
I like Madvapes, but with all due respect, they should be more consistant with giving away items. It makes those of us =) who don't have the free items a bit put off and sometimes I order from someone else when I see others getting free stuff, when I've ordered from them numerous times and had nothing "extra" in the box. Just my honest business oriented opinion.
