Who actually sells magazine space

Nobody sells you "magazines." You buy from one of four animals: a publisher's own ad-sales house, a rep firm selling targeted editions, a performance marketplace, or a shared-mail operator whose product is print without the magazine. Each prices differently, and only one of the eight sellers below publishes a rate card at all.

Which type fits a $10k-$50k quarter

• Buying direct from regional and local titles gives the most page per dollar and full control; it costs your time. This is the default recommendation of this desk.
• Rep-firm targeted editions (MNI) buy national mastheads over regional footprints; quote-only, worth it for prestige-plus-geography.
• Performance marketplaces (Mediabids) shift risk to pay-per-inquiry; strong for call-driven categories.
• Publisher houses (Conde Nast, Hearst, Dotdash Meredith) start above most SMB budgets at full run; their doors are regional editions and remnant.
• Shared mail (Valpak, Vericast) is the local-response alternative when editorial context matters less than the mailbox.

Do you need an agency?

For a handful of titles a quarter: no. The playbook is the job, and card rates build in the agency commission whether or not an agency exists to collect it (Step 02 covers gross vs net). An agency earns its keep when you are coordinating many books, markets and closes at once, or buying categories with genuine scarcity politics.
