my experience has been that first class mail is generally faster than priority and considerably cheaper.

I package as badbug said above, though in lieu of postage I include a buck to cover it. two if'n the mail's headed fro canada.

it shouldn't be a problem, unless you choose to mail w/out using the bubble wrap containers. then sometimes shlitz gets lost.

I've participated in contless swaps and have hosted numerous others and have only had flies lost on two occasions that I can remember. both were with manilla, non-bubble mailers. there's a lesson in that.

I tape the bubble mailers shut too. makes sense to me.
