Speaking of Susan Kirkland, reader Paul Freibott weighed in with his thoughts on Susan's recommendation of budgetmags.com:

This is sort of a Publisher's Clearing House for the dot-com generation. It's almost certain that these are introductory rates that will increase after the initial term (usually one year), since it's standard practice in the industry to lose money on new subscribers by offering low rates. Magazines don't make money on their subscribers until they "convert" or renew at the regular rates. So I wouldn't expect these good rates to last.

Also, re: "professional" rates, in some cases, these
are just a promotional gimmick that serve to flatter
the recipient or make them think they got a secret
deal. For several years now, consumer magazines have
regularly promoted subscription offers to the general
public via direct mail packages marked "professional
rate."

This isn't meant to discourage
anyone from taking advantage of or seeking a good
deal, just to set expectations.

(And if you're wondering, I have a few years experience
in direct marketing, in addition to writing.)

Thanks for the info, Paul!
