Interesting because I am actually leaning towards Prepaid at the moment. I'd be getting atleast 10 satchels to use so that is $7.84 a piece (versus $7.30 C&S) but I won't have to muck around online filling in/importing details, formatting labels, botching up bar codes or printing pages, firing up the printer, running out of ink. Just copy and paste address from order info and instantly spit out a nifty little label via my Dymo Labelwriter. I don't know, it just seems less work and only 54 cents difference in price.
